change above to exevuter under main class name multiple-slider-container

To modify your JavaScript code so that it operates under a main class name `multiple-slider-container`, you'll need to adjust the selectors used to reference the elements. Here's the updated code:

document.addEventListener('DOMContentLoaded', function () {
    const sliderContainer = document.querySelector('.multiple-slider-container');
    const slides = sliderContainer.querySelectorAll('.multiple-slide-simple');
    const prevButton = sliderContainer.querySelector('.prev');
    const nextButton = sliderContainer.querySelector('.next');
    let currentIndex = 0;

    function updateSlider(index) {
        slides.forEach((slide, i) => {
            slide.classList.toggle('active', i === index);
        });

        const offset = -index * 100; // For sliding effect
        sliderContainer.querySelector('.multiple-slider-wrapper-simple').style.transform = `translateX(${offset}%)`;
    }

    prevButton.addEventListener('click', () => {
        currentIndex = (currentIndex > 0) ? currentIndex - 1 : slides.length - 1;
        updateSlider(currentIndex);
    });

    nextButton.addEventListener('click', () => {
        currentIndex = (currentIndex < slides.length - 1) ? currentIndex + 1 : 0;
        updateSlider(currentIndex);
    });
});

### Changes Made:
1. **Scoped Selectors**: The selectors for `slides`, `prevButton`, and `nextButton` now start from the `sliderContainer` to ensure they are all related to the same container with the class `multiple-slider-container`.
2. **Updated `updateSlider` Function**: The selector for the slider wrapper inside `updateSlider` is also scoped to the `sliderContainer`.

This ensures that all operations are performed within the context of the `multiple-slider-container`, which allows for better encapsulation and avoids conflicts with similar classes that might exist elsewhere in your HTML.

what if there are multple classes
Assistant
If there are multiple instances of the `multiple-slider-container` class on the page, and you want to apply the slider functionality to each of them independently, you'll need to loop through each instance of the class and initialize the slider for each one. Here's how you can modify the code to achieve that:

document.addEventListener('DOMContentLoaded', function () {
    const sliderContainers = document.querySelectorAll('.multiple-slider-container');

    sliderContainers.forEach(sliderContainer => {
        const slides = sliderContainer.querySelectorAll('.multiple-slide-simple');
        const prevButton = sliderContainer.querySelector('.prev');
        const nextButton = sliderContainer.querySelector('.next');
        let currentIndex = 0;

        function updateSlider(index) {
            slides.forEach((slide, i) => {
                slide.classList.toggle('active', i === index);
            });

            const offset = -index * 100; // For sliding effect
            sliderContainer.querySelector('.multiple-slider-wrapper-simple').style.transform = `translateX(${offset}%)`;
        }

        prevButton.addEventListener('click', () => {
            currentIndex = (currentIndex > 0) ? currentIndex - 1 : slides.length - 1;
            updateSlider(currentIndex);
        });

        nextButton.addEventListener('click', () => {
            currentIndex = (currentIndex < slides.length - 1) ? currentIndex + 1 : 0;
            updateSlider(currentIndex);
        });
    });
});

### Key Changes:
1. **Looping through Each Container**: The code now uses `document.querySelectorAll('.multiple-slider-container')` to get all instances of the `multiple-slider-container` class and then iterates through each one using `forEach`.
2. **Independent Functionality**: Each slider instance has its own `currentIndex`, `slides`, and button event listeners, allowing them to function independently of each other.

### Additional Considerations:
– Ensure that each `multiple-slider-container` has its own set of `prev`, `next`, `multiple-slide-simple`, and `multiple-slider-wrapper-simple` elements properly structured within it.
– This code will work effectively as long as the HTML structure is consistent across all slider containers.
