Expanding Image Carousel in JavaScript

This code creates an image carousel with expanding panels. Clicking on a panel opens it, revealing a full-screen image. The code uses HTML, CSS, and JavaScript to achieve this effect. It’s a visually appealing way to showcase images or content in a dynamic manner.

It’s great for showcasing products, portfolio items, or featured content in a visually appealing way.

How to Create an Expanding Image Carousel in JavaScript

1. Begin by setting up the HTML structure. Inside your HTML file, create a <div> with the class “panels” and individual panels with the class “panel.” Each panel will contain the content you want to showcase. Make sure to include images in the panel backgrounds.

<div class="panels">
    <div class="panel panel1">
        <p>Whatever</p>
        <p>It</p>
        <p>Takes</p>
    </div>
    <div class="panel panel2">
        <p>Cause</p>
        <p>I</p>
        <p>Love</p>
    </div>
    <div class="panel panel3">
        <p>The</p>
        <p>Adrenaline</p>
        <p>In</p>
    </div>
    <div class="panel panel4">
        <p>My</p>
        <p>Veins</p>
        <p>I</p>
    </div>
    <div class="panel panel5">
        <p>Do</p>
        <p>What It</p>
        <p>Takes !!!</p>
    </div>
</div>

2. Style your panels and define their appearance in the CSS section. You can customize the backgrounds, fonts, and other visual elements to match your website’s design. Add the following CSS code to your project:

html {
    box-sizing: border-box;
    background: #ffc600;
    font-family: 'helvetica neue';
    font-size: 20px;
    font-weight: 200;
}

body {
    margin: 0;
}

*,
*:before,
*:after {
    box-sizing: inherit;
}
.panels {
    height: 100vh;
    overflow: hidden;
    display: flex;
}
.panel{
    box-shadow: inset 0 0 0 5px rgba(255, 255, 255, 0.1);
    color: darkorange;
    text-align: center;
    align-items: center;
    transition:
            font-size 0.7s cubic-bezier(0.61, -0.19, 0.7, -0.11),
            flex 0.7s cubic-bezier(0.61, -0.19, 0.7, -0.11),
            background 0.2s;
    font-size: 20px;
    background: #6B0F9C center;
    background-size: cover;
    display: flex;
    flex-direction: column;
    justify-content: center;
    flex: 1;
}
.panel1{
    background-image: url(https://images.unsplash.com/photo-1526506118085-60ce8714f8c5?ixlib=rb-1.2.1&q=80&fm=jpg&crop=entropy&cs=tinysrgb&w=1080&fit=max&ixid=eyJhcHBfaWQiOjF9);
}
.panel2{

}
.panel3{
    background-image: url(https://images.unsplash.com/photo-1532384748853-8f54a8f476e2?ixlib=rb-1.2.1&q=80&fm=jpg&crop=entropy&cs=tinysrgb&w=1080&fit=max&ixid=eyJhcHBfaWQiOjF9);
}
.panel4{
    background-image: url(https://images.unsplash.com/photo-1434596922112-19c563067271?ixlib=rb-1.2.1&q=80&fm=jpg&crop=entropy&cs=tinysrgb&w=1080&fit=max&ixid=eyJhcHBfaWQiOjF9);
}
.panel5{
    background-image: url(https://images.unsplash.com/photo-1506197061617-7f5c0b093236?ixlib=rb-1.2.1&q=80&fm=jpg&crop=entropy&cs=tinysrgb&w=1080&fit=max&ixid=eyJhcHBfaWQiOjF9);
}
/*Flex Children*/
.panel>* {
    margin: 0;
    width: 100%;
    transition: transform 0.5s;
    display: flex;
    flex: 1 0 auto;
    justify-content: center;
    align-items: center;
}
.panel>*:first-child{
    transform: translateY(-100%);
}
.panel.open-active>*:first-child{
    transform: translateY(0);
}
.panel>*:last-child{
    transform: translateY(100%);
}
.panel.open-active>*:last-child{
    transform: translateY(0);
}
.panel p {
    text-transform: uppercase;
    font-family: 'Amatic SC', cursive;
    text-shadow: 0 0 4px rgba(0, 0, 0, 0.72), 0 0 14px rgba(0, 0, 0, 0.45);
    font-size: 2em;
}
.panel p:nth-child(2) {
    font-size: 4em;
}

.panel.open {
    font-size: 40px;
    flex: 5;
}

3. To make the panels expand and contract, we’ll use JavaScript. Include the following JavaScript code in your HTML file. It adds interactivity to the panels, making them expand when clicked.

const panels = document.querySelectorAll('.panel');
    function toggleOpen() {
        this.classList.toggle('open')
    }
    function toggleActive(e){
        if(e.propertyName.includes('flex')){
            this.classList.toggle('open-active')
        }
    }

    panels.forEach((panel)=>panel.addEventListener('click',toggleOpen));
    panels.forEach((panel)=>panel.addEventListener('transitionend',toggleActive));
