To achieve a smooth hover effect for your overlay items, you can utilize CSS transitions and adjust the JavaScript code slightly to manage the visibility and transformations of the overlay items effectively. Below is an updated version of your JavaScript code with enhancements for smoother animations and effects:

### CSS for Smooth Transitions
First, make sure you have some CSS styles to apply transitions on the `content` and `description` elements. Add these styles to your CSS file:

.hover-item .content,
.hover-item .description {
    transition: opacity 0.5s ease, transform 0.5s ease; /* Smooth fade and transform */
    opacity: 0; /* Initially hidden */
    transform: translateY(20px); /* Slightly moved down */
}

.hover-item .content.active,
.hover-item .description.active {
    opacity: 1; /* Fully visible */
    transform: translateY(0); /* Move to original position */
}

### Updated JavaScript
Here’s the updated JavaScript to ensure that hover items open and close smoothly:

const $overlaySliderGrid = $('.overlay-slider-grid');
const $overlayslider = $('.overlay-slider');
const $mainparent = $overlaySliderGrid.find('.content-overlayslider');
const $hoverItems = $mainparent.find('.hover-item');

let currentIndex = 0; // For tracking the selected item for keyboard navigation or scroll
let xPos = 0; // Initialize xPos
let yPos = 0; // Initialize yPos

// Function to update background and content
const updateSlider = ($item) => {
    const newBg = $item.data('bg');
    $overlayslider.css('background-image', `url(${newBg})`);

    $item.find('.content').addClass('active');
    $item.find('.description').addClass('active');
    $item.siblings().find('.content, .description').removeClass('active');
};

// Scroll event for hover items
$hoverItems.on('wheel', function () {
    updateSlider($(this));
});

$hoverItems.on('mouseenter', function () {
    updateSlider($(this));
});

// Keyboard navigation (up/down arrow keys)
$(document).on('keydown', function (e) {
    if (e.key === 'ArrowUp') {
        currentIndex = (currentIndex - 1 + $hoverItems.length) % $hoverItems.length;
        updateSlider($hoverItems.eq(currentIndex));
    } else if (e.key === 'ArrowDown') {
        currentIndex = (currentIndex + 1) % $hoverItems.length;
        updateSlider($hoverItems.eq(currentIndex));
    }
});

// Intersection Observer to detect visibility of the overlay-slider-grid
const observerOptions = {
    root: null,
    rootMargin: '0px',
    threshold: 0.5
};

const observer = new IntersectionObserver((entries) => {
    entries.forEach((entry) => {
        if (entry.isIntersecting) {
            $mainparent.addClass('visible');
            $hoverItems.eq(currentIndex).trigger('wheel'); // Trigger initial update
        } else {
            $mainparent.removeClass('visible');
        }
    });
}, observerOptions);

observer.observe($overlaySliderGrid[0]);

// Browser scrollbar event to update content
$(window).on('scroll', function () {
    const scrollTop = $(window).scrollTop();
    const overlayOffset = $overlaySliderGrid.offset().top;
    const overlayHeight = $overlaySliderGrid.outerHeight();

    if (scrollTop >= overlayOffset && scrollTop <= overlayOffset + overlayHeight) {
        const relativeScroll = (scrollTop - overlayOffset) / overlayHeight; // 0 to 1 range
        const newIndex = Math.floor(relativeScroll * $hoverItems.length);

        if (newIndex !== currentIndex) {
            currentIndex = newIndex;
            updateSlider($hoverItems.eq(currentIndex));
        }
    }
});

### Explanation of Changes
– **CSS Transitions:** The added CSS rules apply a transition effect to the `.content` and `.description` elements. They will fade in and move up into position smoothly when the `active` class is added.
– **JavaScript Logic:** The logic for updating the slider remains the same, ensuring that the correct items are activated based on hover and scroll events.

### Additional Tips
– Make sure your jQuery and CSS files are properly linked in your HTML document.
– You can further customize the transition duration and easing functions in the CSS to achieve the desired effect.

This setup will provide a smooth and visually appealing hover effect for your overlay items, enhancing the user experience.

by default show content heading in normal and hover then apply current effect with smooth like above
Assistant
To achieve a smooth hover effect where the content heading is displayed normally by default and then applies the hover effects on mouse enter while maintaining a smooth transition, you can modify the JavaScript and CSS as follows:

### CSS for Default and Hover States
Update your CSS to show the content heading normally and apply the hover effect only when hovered:

.hover-item .content,
.hover-item .description {
    transition: opacity 0.5s ease, transform 0.5s ease; /* Smooth fade and transform */
    opacity: 0; /* Initially hidden */
    transform: translateY(20px); /* Slightly moved down */
}

.hover-item.active .content,
.hover-item.active .description {
    opacity: 1; /* Fully visible */
    transform: translateY(0); /* Move to original position */
}

/* Make sure the heading is visible normally */
.hover-item .content {
    opacity: 1; /* Keep the content visible by default */
    transform: translateY(0); /* No transformation by default */
}

### Updated JavaScript for Active Class Management
Here’s the updated JavaScript code that ensures the heading is displayed normally and applies the hover effects correctly:

const $overlaySliderGrid = $('.overlay-slider-grid');
const $overlayslider = $('.overlay-slider');
const $mainparent = $overlaySliderGrid.find('.content-overlayslider');
const $hoverItems = $mainparent.find('.hover-item');

let currentIndex = 0; // For tracking the selected item for keyboard navigation or scroll
let xPos = 0; // Initialize xPos
let yPos = 0; // Initialize yPos

// Function to update background and content
const updateSlider = ($item) => {
    const newBg = $item.data('bg');
    $overlayslider.css('background-image', `url(${newBg})`);

    // Set the active class on the current item
    $hoverItems.removeClass('active'); // Remove active class from all
    $item.addClass('active'); // Add active class to the current item

    // Fade in/out content and description based on active item
    $hoverItems.find('.content, .description').removeClass('active');
    $item.find('.content').addClass('active'); // Keep the content visible
    $item.find('.description').addClass('active'); // Show description on hover
};

// Scroll event for hover items
$hoverItems.on('wheel', function () {
    updateSlider($(this));
});

$hoverItems.on('mouseenter', function () {
    updateSlider($(this));
});

// Keyboard navigation (up/down arrow keys)
$(document).on('keydown', function (e) {
    if (e.key === 'ArrowUp') {
        currentIndex = (currentIndex - 1 + $hoverItems.length) % $hoverItems.length;
        updateSlider($hoverItems.eq(currentIndex));
    } else if (e.key === 'ArrowDown') {
        currentIndex = (currentIndex + 1) % $hoverItems.length;
        updateSlider($hoverItems.eq(currentIndex));
    }
});

// Intersection Observer to detect visibility of the overlay-slider-grid
const observerOptions = {
    root: null,
    rootMargin: '0px',
    threshold: 0.5
};

const observer = new IntersectionObserver((entries) => {
    entries.forEach((entry) => {
        if (entry.isIntersecting) {
            $mainparent.addClass('visible');
            $hoverItems.eq(currentIndex).trigger('wheel'); // Trigger initial update
        } else {
            $mainparent.removeClass('visible');
        }
    });
}, observerOptions);

observer.observe($overlaySliderGrid[0]);

// Browser scrollbar event to update content
$(window).on('scroll', function () {
    const scrollTop = $(window).scrollTop();
    const overlayOffset = $overlaySliderGrid.offset().top;
    const overlayHeight = $overlaySliderGrid.outerHeight();

    if (scrollTop >= overlayOffset && scrollTop <= overlayOffset + overlayHeight) {
        const relativeScroll = (scrollTop - overlayOffset) / overlayHeight; // 0 to 1 range
        const newIndex = Math.floor(relativeScroll * $hoverItems.length);

        if (newIndex !== currentIndex) {
            currentIndex = newIndex;
            updateSlider($hoverItems.eq(currentIndex));
        }
    }
});

### Key Changes Explained
– **CSS Modifications:**
– The `.content` now has `opacity: 1` and `transform: translateY(0)` by default, ensuring it is always visible unless a hover effect is applied. This allows the heading to be shown normally.
– The active class is applied to the `.hover-item`, which triggers the hover effects smoothly when an item is hovered over.

– **JavaScript Logic:**
– The `updateSlider` function now manages the `active` class on the hover items and ensures that the content remains visible while still allowing for the description to show on hover.

This setup will show the content heading normally by default and smoothly apply the hover effects when the user interacts with the items, providing an engaging user experience.

User
but now description now showinh
Assistant
To ensure the description appears smoothly on hover while keeping the content heading visible by default, we need to adjust the CSS and JavaScript logic to control the visibility and transitions properly.

Here’s how you can modify your setup to achieve this:

### Updated CSS
We'll adjust the CSS to ensure the heading is visible by default, and the description appears on hover with a smooth transition:

.hover-item {
    position: relative; /* Ensure positioning context for absolute children */
}

.hover-item .content {
    opacity: 1; /* Keep the content heading visible by default */
    transform: translateY(0); /* No transformation by default */
    transition: opacity 0.5s ease, transform 0.5s ease; /* Smooth transition */
}

.hover-item .description {
    opacity: 0; /* Initially hidden */
    transform: translateY(20px); /* Slightly moved down */
    transition: opacity 0.5s ease, transform 0.5s ease; /* Smooth transition */
}

.hover-item.active .description {
    opacity: 1; /* Fully visible on hover */
    transform: translateY(0); /* Move to original position */
}

### Updated JavaScript
We need to make sure the JavaScript correctly adds the `active` class to the current item while ensuring the description appears:

const $overlaySliderGrid = $('.overlay-slider-grid');
const $overlayslider = $('.overlay-slider');
const $mainparent = $overlaySliderGrid.find('.content-overlayslider');
const $hoverItems = $mainparent.find('.hover-item');

let currentIndex = 0; // For tracking the selected item for keyboard navigation or scroll

// Function to update background and content
const updateSlider = ($item) => {
    const newBg = $item.data('bg');
    $overlayslider.css('background-image', `url(${newBg})`);

    // Set the active class on the current item
    $hoverItems.removeClass('active'); // Remove active class from all
    $item.addClass('active'); // Add active class to the current item

    // This ensures the content heading remains visible
    $item.find('.description').addClass('active'); // Show description on hover
};

// Scroll event for hover items
$hoverItems.on('wheel', function () {
    updateSlider($(this));
});

$hoverItems.on('mouseenter', function () {
    updateSlider($(this));
});

// Keyboard navigation (up/down arrow keys)
$(document).on('keydown', function (e) {
    if (e.key === 'ArrowUp') {
        currentIndex = (currentIndex - 1 + $hoverItems.length) % $hoverItems.length;
        updateSlider($hoverItems.eq(currentIndex));
    } else if (e.key === 'ArrowDown') {
        currentIndex = (currentIndex + 1) % $hoverItems.length;
        updateSlider($hoverItems.eq(currentIndex));
    }
});

// Intersection Observer to detect visibility of the overlay-slider-grid
const observerOptions = {
    root: null,
    rootMargin: '0px',
    threshold: 0.5
};

const observer = new IntersectionObserver((entries) => {
    entries.forEach((entry) => {
        if (entry.isIntersecting) {
            $mainparent.addClass('visible');
            $hoverItems.eq(currentIndex).trigger('wheel'); // Trigger initial update
        } else {
            $mainparent.removeClass('visible');
        }
    });
}, observerOptions);

observer.observe($overlaySliderGrid[0]);

// Browser scrollbar event to update content
$(window).on('scroll', function () {
    const scrollTop = $(window).scrollTop();
    const overlayOffset = $overlaySliderGrid.offset().top;
    const overlayHeight = $overlaySliderGrid.outerHeight();

    if (scrollTop >= overlayOffset && scrollTop <= overlayOffset + overlayHeight) {
        const relativeScroll = (scrollTop - overlayOffset) / overlayHeight; // 0 to 1 range
        const newIndex = Math.floor(relativeScroll * $hoverItems.length);

        if (newIndex !== currentIndex) {
            currentIndex = newIndex;
            updateSlider($hoverItems.eq(currentIndex));
        }
    }
});

### Explanation of Changes
1. **CSS Adjustments:**
– The `.description` is initially hidden with `opacity: 0` and will translate down. When the item is hovered over, the `active` class is added to `.description`, making it `opacity: 1` and transitioning to its original position smoothly.
– The `.content` remains fully visible and doesn't change opacity or position on hover.

2. **JavaScript Logic:**
– The `updateSlider` function adds the `active` class to both the hovered item's content and description, ensuring the description appears smoothly when the item is hovered over.

### Result
With these changes, the heading will be visible by default, and the description will fade in and move into view smoothly when the user hovers over the corresponding item. This approach ensures a clean and engaging user experience.

little slow make affect slow outing from hide
Assistant
To make the hover effect slower when the description appears and disappears, you can adjust the CSS transition duration for the `.description`. Here’s how to do that:

### Updated CSS
Increase the transition duration for the `.description` to make the fade-in and fade-out effects slower:

.hover-item .description {
    opacity: 0; /* Initially hidden */
    transform: translateY(20px); /* Slightly moved down */
    transition: opacity 0.8s ease, transform 0.8s ease; /* Smooth transition, increased duration */
}

.hover-item.active .description {
    opacity: 1; /* Fully visible on hover */
    transform: translateY(0); /* Move to original position */
}

### Full CSS Example
Here’s the complete CSS with the updated transition duration:

.hover-item {
    position: relative; /* Ensure positioning context for absolute children */
}

.hover-item .content {
    opacity: 1; /* Keep the content heading visible by default */
    transform: translateY(0); /* No transformation by default */
    transition: opacity 0.5s ease, transform 0.5s ease; /* Smooth transition */
}

.hover-item .description {
    opacity: 0; /* Initially hidden */
    transform: translateY(20px); /* Slightly moved down */
    transition: opacity 0.8s ease, transform 0.8s ease; /* Smooth transition with increased duration */
}

.hover-item.active .description {
    opacity: 1; /* Fully visible on hover */
    transform: translateY(0); /* Move to original position */
}

### Explanation of Changes
– **Transition Duration:** The transition duration for the `.description` class has been increased to `0.8s` for both the `opacity` and `transform` properties. You can adjust this value further if you want an even slower effect.

### Result
With these changes, the description will fade in and out more slowly, creating a smoother and more gradual effect when hovering over the items. Feel free to adjust the duration further (e.g., `1s`) if you want to make it even slower!

User
make affect like its coming from behind the current hover item div
Assistant
To create an effect where the description appears as if it's coming from behind the current hover item, we can use CSS transformations to position the description initially behind the item. We'll adjust the `z-index` and apply a transform to make it look like it's sliding in from behind when hovered.

Here’s how you can achieve this:

### Updated CSS
1. Set the initial position of the `.description` behind the `.hover-item` using negative translation and a lower `z-index`.
2. On hover, adjust the `z-index` and transform properties to make it slide in from behind.

.hover-item {
    position: relative; /* Ensure positioning context */
    overflow: hidden; /* Hide overflow to prevent showing behind content */
}

.hover-item .content {
    opacity: 1; /* Keep the content heading visible by default */
    transform: translateY(0); /* No transformation by default */
    transition: opacity 0.5s ease, transform 0.5s ease; /* Smooth transition */
}

.hover-item .description {
    opacity: 0; /* Initially hidden */
    transform: translateY(20px); /* Move down */
    z-index: -1; /* Position behind the content */
    transition: opacity 0.8s ease, transform 0.8s ease; /* Smooth transition with increased duration */
}

.hover-item.active .description {
    opacity: 1; /* Fully visible on hover */
    transform: translateY(0); /* Move to original position */
    z-index: 1; /* Bring it in front of the content */
}

.hover-item.active .content {
    z-index: 0; /* Keep content in the background when description is active */
}

### Explanation of CSS Changes
– **Initial State of `.description`:**
– Set `z-index: -1` to ensure the description starts behind the content.
– The description is translated down by `20px` to initially position it below.

– **Hover State:**
– On hover, when the `.hover-item` is active, the description’s `z-index` is set to `1`, bringing it in front of the content, and its `opacity` is set to `1`.
– The `transform` property moves the description to its original position.

### Updated JavaScript (No Changes Needed)
Your existing JavaScript code does not need any changes since the logic for adding the `active` class remains the same. It will work with the updated CSS to trigger the hover effects.

### Result
With these changes, the description will appear to slide in from behind the current hover item, creating a more dynamic and engaging effect as if it’s coming forward. You can further tweak the transform values or transition durations to fine-tune the effect according to your preferences.

User
make little slower
Assistant
To slow down the effect of the description coming from behind the current hover item, you can increase the duration of the transitions in the CSS. Here’s the updated CSS with slower transitions for the `.description`:

### Updated CSS with Slower Transitions

.hover-item {
    position: relative; /* Ensure positioning context */
    overflow: hidden; /* Hide overflow to prevent showing behind content */
}

.hover-item .content {
    opacity: 1; /* Keep the content heading visible by default */
    transform: translateY(0); /* No transformation by default */
    transition: opacity 0.5s ease, transform 0.5s ease; /* Smooth transition */
}

.hover-item .description {
    opacity: 0; /* Initially hidden */
    transform: translateY(20px); /* Move down */
    z-index: -1; /* Position behind the content */
    transition: opacity 1s ease, transform 1s ease; /* Increased duration for smoother effect */
}

.hover-item.active .description {
    opacity: 1; /* Fully visible on hover */
    transform: translateY(0); /* Move to original position */
    z-index: 1; /* Bring it in front of the content */
}

.hover-item.active .content {
    z-index: 0; /* Keep content in the background when description is active */
}

### Key Changes
– **Increased Transition Duration:** The duration for the `opacity` and `transform` properties of the `.description` has been increased to `1s`. You can adjust this further to make it even slower, such as `1.2s` or `1.5s`, depending on your preference.

### Example of Further Adjustment
If you want to make it even slower, you can modify the transition duration like this:

.hover-item .description {
    transition: opacity 1.5s ease, transform 1.5s ease; /* Even slower effect */
}

### Result
With these changes, the description will now slide in from behind the current hover item more slowly, providing a smoother and more gradual effect. You can continue to adjust the timing until it fits your desired pace!

User
hiden default content heading and make effect comping from behind the div
Assistant
To achieve an effect where the default content heading is hidden and the description appears to come from behind the current hover item, you can follow these steps:

1. **Hide the default content heading initially.**
2. **Use CSS transitions to create the sliding effect for the description.**

Here’s how you can implement this:

### Updated HTML Structure
Make sure your HTML structure allows for the description to be positioned properly behind the content. You can keep your existing structure if it already accommodates this:

<div class="overlay-slider-grid">
    <div class="overlay-slider">
        <div class="hover-item">
            <div class="content">Content Heading</div>
            <div class="description">Description Here</div>
        </div>
        <!-- Repeat for other hover items -->
    </div>
</div>

### Updated CSS
1. **Hide the content heading by default.**
2. **Apply transformations and transitions for the description to give the effect of coming from behind.**

.hover-item {
    position: relative; /* Ensure positioning context */
    overflow: hidden; /* Hide overflow to prevent showing behind content */
}

.hover-item .content {
    opacity: 0; /* Hide content heading by default */
    transform: translateY(20px); /* Move down to start position */
    transition: opacity 0.5s ease, transform 0.5s ease; /* Smooth transition */
}

.hover-item .description {
    opacity: 0; /* Initially hidden */
    transform: translateY(20px); /* Start position moved down */
    z-index: -1; /* Position behind the content */
    transition: opacity 1s ease, transform 1s ease; /* Increased duration for smoother effect */
}

.hover-item.active .content {
    opacity: 1; /* Show content on hover */
    transform: translateY(0); /* Move to original position */
}

.hover-item.active .description {
    opacity: 1; /* Fully visible on hover */
    transform: translateY(0); /* Move to original position */
    z-index: 1; /* Bring it in front of the content */
}

### Explanation of CSS Changes
– **Default State for `.content`:**
– Set `opacity: 0` to hide the content heading by default.
– Apply a `transform: translateY(20px)` to move it down.

– **Transition on Hover:**
– When the `.hover-item` is active, the content heading will transition to `opacity: 1` and `transform: translateY(0)` to show it moving into place.
– The description also transitions from hidden to visible and moves into place, creating the effect of coming from behind.

### Updated JavaScript (No Changes Needed)
The existing JavaScript code for managing the active state remains unchanged. It will trigger the active class on the hovered item, which in turn will apply the CSS transitions.

### Result
With these changes, the default content heading will be hidden, and when you hover over an item, the description will appear to slide in from behind the item smoothly. You can adjust the transition durations as needed for your desired effect!

Assistant
To create an effect where the default content heading is not hidden but instead is shown to appear as if it’s coming from behind the current hover item when hovered over or scrolled, you can follow these steps:

1. **Keep the content visible by default.**
2. **Apply a translation and transition effect to the description to create the illusion that it’s sliding in from behind.**

### Updated CSS

Here’s how to implement this effect:

.hover-item {
    position: relative; /* Ensure positioning context */
    overflow: hidden; /* Hide overflow to prevent showing behind content */
}

.hover-item .content {
    opacity: 1; /* Keep content heading visible */
    transform: translateY(0); /* No transformation */
    transition: opacity 0.5s ease, transform 0.5s ease; /* Smooth transition */
}

.hover-item .description {
    opacity: 0; /* Initially hidden */
    transform: translateY(20px); /* Move down initially */
    z-index: -1; /* Position behind the content */
    transition: opacity 0.8s ease, transform 0.8s ease; /* Smooth transition with duration */
}

.hover-item:hover .description,
.hover-item.active .description {
    opacity: 1; /* Fully visible on hover or when active */
    transform: translateY(0); /* Move to original position */
    z-index: 1; /* Bring it in front of the content */
}

.hover-item:hover .content,
.hover-item.active .content {
    z-index: 0; /* Ensure content stays behind when description is visible */
    transform: translateY(-10px); /* Slightly move the content up for the effect */

– **Content State:**
– The `.content` remains visible with `opacity: 1` and is translated to its original position. It has a small upward movement when the description is shown, giving a layered effect.

– **Description State:**
– The `.description` starts hidden (`opacity: 0` and `transform: translateY(20px)`) to appear as if it's coming from below.

– **Hover State:**
– On hover or when the item is active, the `.description` transitions to `opacity: 1` and `transform: translateY(0)`, making it visible and positioned correctly in front of the content.
– The `.content` moves slightly up to enhance the perception that the description is coming from behind.

### Updated JavaScript (No Changes Needed)
You can continue using the existing JavaScript code to manage the hover and scroll events without any modifications.

### Result
With these changes, the content heading will remain visible, and the description will slide in smoothly from behind when you hover over the item or scroll. You can adjust the transition durations and transform values as needed to perfect the effect for your design!

// });
};

// Scroll event for hover items

updateSlider($(this));

});
$hoverItems.on('mouseenter', function () {
updateSlider($(this));
});
// Keyboard navigation (up/down arrow keys)

if (e.key === 'ArrowUp') {

updateSlider($hoverItems.eq(currentIndex));
} else if (e.key === 'ArrowDown') {

updateSlider($hoverItems.eq(currentIndex));
}
});

// Intersection Observer to detect visibility of the overlay-slider-grid
const observerOptions = {
root: null,
rootMargin: '0px',
threshold: 0.5
};

const observer = new IntersectionObserver((entries) => {
entries.forEach((entry) => {
if (entry.isIntersecting) {
$mainparent.addClass('visible');
$hoverItems.eq(currentIndex).trigger('wheel'); // Trigger initial update
} else {
$mainparent.removeClass('visible');
}
});
}, observerOptions);

observer.observe($overlaySliderGrid[0]);

// Browser scrollbar event to update content
$(window).on('scroll', function () {
const scrollTop = $(window).scrollTop();
const overlayOffset = $overlaySliderGrid.offset().top;
const overlayHeight = $overlaySliderGrid.outerHeight();

if (scrollTop >= overlayOffset && scrollTop

Assistant
To achieve the effect where the content updates on mouse wheel events when hovering over the overlay slider grid, you can modify the existing code to add a mouse enter event that enables wheel scrolling specifically for the grid. Below are the steps to implement this:

1. **Add a `mouseenter` event listener on the overlay slider grid to enable scrolling.**
2. **Handle the wheel event when the mouse is over the grid.**

### Updated JavaScript

Here's the modified code:

if ($('.overlay-slider-grid').length) {
    const $overlaySliderGrid = $('.overlay-slider-grid');
    const $overlayslider = $('.overlay-slider');
    const $mainparent = $overlaySliderGrid.find('.content-overlayslider');
    const $hoverItems = $mainparent.find('.hover-item');

    let currentIndex = 0; // For tracking the selected item for keyboard navigation or scroll
    let xPos = 0; // Initialize xPos
    let yPos = 0; // Initialize yPos

    // Function to update background and content
    const updateSlider = ($item) => {
        const newBg = $item.data('bg');
        $overlayslider.css('background-image', `url(${newBg})`);

        $item.find('.content').addClass('active');
        $item.find('.description').addClass('active');
        $item.siblings().find('.content, .description').removeClass('active');
    };

    // Mouse wheel event for the overlay slider grid
    $overlaySliderGrid.on('wheel', function (event) {
        event.preventDefault(); // Prevent default scroll behavior

        // Determine scroll direction
        if (event.originalEvent.deltaY > 0) {
            // Scroll down
            currentIndex = (currentIndex + 1) % $hoverItems.length;
        } else {
            // Scroll up
            currentIndex = (currentIndex - 1 + $hoverItems.length) % $hoverItems.length;
        }

        updateSlider($hoverItems.eq(currentIndex));
    });

    // Keyboard navigation (up/down arrow keys)
    $(document).on('keydown', function (e) {
        if (e.key === 'ArrowUp') {
            currentIndex = (currentIndex - 1 + $hoverItems.length) % $hoverItems.length;
            updateSlider($hoverItems.eq(currentIndex));
        } else if (e.key === 'ArrowDown') {
            currentIndex = (currentIndex + 1) % $hoverItems.length;
            updateSlider($hoverItems.eq(currentIndex));
        }
    });

    // Intersection Observer to detect visibility of the overlay-slider-grid
    const observerOptions = {
        root: null,
        rootMargin: '0px',
        threshold: 0.5
    };

    const observer = new IntersectionObserver((entries) => {
        entries.forEach((entry) => {
            if (entry.isIntersecting) {
                $mainparent.addClass('visible');
                $hoverItems.eq(currentIndex).trigger('wheel'); // Trigger initial update
            } else {
                $mainparent.removeClass('visible');
            }
        });
    }, observerOptions);

    observer.observe($overlaySliderGrid[0]);

    // Browser scrollbar event to update content
    $(window).on('scroll', function () {
        const scrollTop = $(window).scrollTop();
        const overlayOffset = $overlaySliderGrid.offset().top;
        const overlayHeight = $overlaySliderGrid.outerHeight();

        if (scrollTop >= overlayOffset && scrollTop <= overlayOffset + overlayHeight) {
            const relativeScroll = (scrollTop - overlayOffset) / overlayHeight; // 0 to 1 range
            const newIndex = Math.floor(relativeScroll * $hoverItems.length);

            if (newIndex !== currentIndex) {
                currentIndex = newIndex;
                updateSlider($hoverItems.eq(currentIndex));
            }
        }
    });
}

### Key Changes Made

1. **Mouse Wheel Event:**
– Added an event listener for the mouse wheel on the `$overlaySliderGrid` that determines the scroll direction based on `event.originalEvent.deltaY`.
– Depending on the scroll direction, it updates the `currentIndex` accordingly.

2. **Prevent Default Behavior:**
– Used `event.preventDefault()` to prevent the default scrolling behavior, allowing you to control the effect entirely through your custom logic.

### Result
With these changes, when the mouse is over the overlay slider grid and the wheel is scrolled, the effect will simulate scrolling through the items as defined by your hover items, making it feel like a natural interaction. Adjust the behavior and transitions as necessary to fit your design requirements!
