we have to apply some scrolling when above area visible after scroll
### **Approach:**
1. Use the **Intersection Observer API** to detect when the `.red-banner` is in view.
2. Apply a smooth scrolling effect when the section becomes visible.

### **Solution:**
#### **1. Add CSS for Smooth Scrolling Effect**
.red-banner {
transition: transform 0.6s ease-in-out, opacity 0.6s ease-in-out;
transform: translateY(50px);
opacity: 0;
}
.red-banner.scrolled {
transform: translateY(0);
opacity: 1;
}—
#### **2. Add JavaScript for Intersection Observer**
document.addEventListener("DOMContentLoaded", function () {
let redBanner = document.querySelector(".red-banner");
if (redBanner) {
let observer = new IntersectionObserver(
function (entries) {
entries.forEach(entry => {
if (entry.isIntersecting) {
redBanner.classList.add("scrolled");
} else {
redBanner.classList.remove("scrolled");
}
});
},
{ threshold: 0.3 } // Adjust threshold to trigger effect earlier/later
);
observer.observe(redBanner);
}
});—
### **How This Works:**
– The `.red-banner` starts with `opacity: 0` and is slightly shifted down using `transform: translateY(50px)`.
– When it enters the viewport (30% visible), we add the `.scrolled` class.
– The `scrolled` class smoothly moves it into place and fades it in.
—
#### **Alternative (jQuery Version)**
If you're using jQuery, you can achieve a similar effect:
jQuery(document).ready(function ($) {
$(window).on("scroll", function () {
let banner = $(".red-banner");
let bannerOffset = banner.offset().top;
let scrollPos = $(window).scrollTop() + $(window).height();
if (scrollPos > bannerOffset + 100) {
banner.addClass("scrolled");
} else {
banner.removeClass("scrolled");
}
});
});—
### **Final Thoughts**
– This method ensures the effect triggers only when the user scrolls to the section.
– If you want a **one-time** animation, you can remove the `else` condition in the `IntersectionObserver` code.
Would you like to add additional effects, like a parallax effect? 🚀

### **Approach**
1. **Detect when the `.red-banner` is about to enter the viewport** after scrolling past the image.
2. **Apply a smooth scrolling effect** to the `.red-banner`.
3. **Ensure the effect triggers only when the section is fully visible**.
—
### **Solution**
#### **1. Add CSS for the Scrolling Effect**
.red-banner {
transition: transform 0.6s ease-in-out, opacity 0.6s ease-in-out;
transform: translateY(50px);
opacity: 0;
}
.red-banner.scrolled {
transform: translateY(0);
opacity: 1;
}– Initially, the `.red-banner` is slightly **pushed down** and **hidden**.
– When scrolled into view, it **fades in and moves up smoothly**.
—
#### **2. Use JavaScript (Intersection Observer)**
document.addEventListener("DOMContentLoaded", function () {
let redBanner = document.querySelector(".red-banner");
if (redBanner) {
let observer = new IntersectionObserver(
function (entries) {
entries.forEach(entry => {
if (entry.isIntersecting) {
redBanner.classList.add("scrolled");
}
});
},
{
root: null, // Uses viewport
threshold: 0.5 // Triggers when 50% of the section is visible
}
);
observer.observe(redBanner);
}
});– The animation **only triggers when at least 50% of the `.red-banner` is visible**.
– The effect will **not repeat when scrolling up and down**.
—
### **Alternative: jQuery Version**
If you're using jQuery, you can use this:
jQuery(document).ready(function ($) {
$(window).on("scroll", function () {
let banner = $(".red-banner");
let img = $(".your-image-class"); // Replace with actual image class
let bannerOffset = banner.offset().top;
let scrollPos = $(window).scrollTop() + $(window).height();
if (scrollPos > bannerOffset + 50) {
banner.addClass("scrolled");
}
});
});—
### **Final Touch**
If you want to make sure the animation is smooth, add this:
html {
scroll-behavior: smooth;
}—
### **Next Steps**
– Do you want to add **parallax scrolling** for the image above the `.red-banner`?
– Would you like a **different animation effect** (e.g., fade-in from the left or right)?

### **CSS Implementation**
.red-banner::before {
content: "";
display: block;
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
background: inherit; /* If you want it to inherit the red banner background */
transform: translateX(2%);
transition: transform 0.6s ease-in-out;
}
.red-banner {
position: relative;
transition: transform 0.6s ease-in-out, opacity 0.6s ease-in-out;
transform: translateY(50px);
opacity: 0;
}
.red-banner.scrolled {
transform: translateY(0);
opacity: 1;
}
.red-banner.scrolled::before {
transform: translateX(0); /* Move back to original position */
}—
### **JavaScript (Intersection Observer)**
document.addEventListener("DOMContentLoaded", function () {
let redBanner = document.querySelector(".red-banner");
if (redBanner) {
let observer = new IntersectionObserver(
function (entries) {
entries.forEach(entry => {
if (entry.isIntersecting) {
redBanner.classList.add("scrolled");
}
});
},
{ threshold: 0.5 } // Adjust trigger point
);
observer.observe(redBanner);
}
});—
### **How This Works**
1. **Before Scrolling:**
– `.red-banner` is slightly **shifted down (`translateY(50px)`) and hidden (`opacity: 0`)**.
– `.red-banner::before` is **shifted right by 2% (`translateX(2%)`)**.
2. **After Scrolling into View:**
– `.red-banner` **moves up (`translateY(0)`) and fades in (`opacity: 1`)**.
– `.red-banner::before` **moves back to its original position (`translateX(0)`)**.
—
### **Next Steps**
Would you like to add **a delay** or **different animations (e.g., sliding from the left or right)?** 🚀
.red-banner::before {
content: "";
display: block;
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
background: inherit;
transition: transform 0.6s ease-in-out;
}
Now I want to apply transform: translatex(2%); when red-banner is vsible

### **Updated CSS**
.red-banner {
position: relative;
transition: opacity 0.6s ease-in-out, transform 0.6s ease-in-out;
opacity: 0;
transform: translateY(50px); /* Initially shifted down */
}
.red-banner::before {
content: "";
display: block;
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
background: inherit;
transform: translateX(0); /* Default position */
transition: transform 0.6s ease-in-out;
}
/* When the section is visible */
.red-banner.scrolled {
opacity: 1;
transform: translateY(0);
}
.red-banner.scrolled::before {
transform: translateX(2%); /* Apply transform when visible */
}—
### **JavaScript to Detect Visibility**
document.addEventListener("DOMContentLoaded", function () {
let redBanner = document.querySelector(".red-banner");
if (redBanner) {
let observer = new IntersectionObserver(
function (entries) {
entries.forEach(entry => {
if (entry.isIntersecting) {
redBanner.classList.add("scrolled");
}
});
},
{
threshold: 0.5 // Trigger when 50% of the element is visible
}
);
observer.observe(redBanner);
}
});—
### **How This Works**
1. **Before Scrolling:**
– `.red-banner` is **hidden (`opacity: 0`)** and **shifted down (`translateY(50px)`)**.
– `.red-banner::before` is at **`translateX(0)` (default position)**.
2. **After Scrolling into View:**
– `.red-banner` becomes **fully visible (`opacity: 1`)** and moves up (`translateY(0)`).
– `.red-banner::before` shifts **2% to the right (`translateX(2%)`)**.
—
### **Additional Customization**
– Want a **stronger effect**? Increase `translateX(2%)` to `translateX(5%)`.
– Need **delayed animation**? Add `animation-delay: 0.3s;` to `.red-banner.scrolled::before`.
