How To Create Ripple Animation Button In HTML CSS And Javascript | letsbug

     Hi, today we are creating a ripple animation on a button using HTML CSS and Javascript. We are going to implement this feature in a way that we can use the code multiple times basically D.R.Y. 

    Ripple Animation Button

code:

index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>ripple Effect</title>
    <link rel="stylesheet" href="./style.css">
    <script src="./script.js" defer  ></script>
</head>
<body>
    <button class="ripple-btn">CLICK me</button>
    <button class="ripple-btn">hello</button>
</body>
</html>

styles.css

*{
    margin:0;
    padding: 0;
    box-sizing: border-box;
}

body{
    min-height: 100vh;
    display: grid;
    place-items: center;
    font-family: system-ui;
}

.ripple-btn{
    appearance: none;
    position: relative;
    display: inline-grid;
    place-items: center;
    isolation: isolate;
    font-size: 3em;
    font-weight: 500;
    padding: 1em 3em;
    text-transform: uppercase;
    background-color: transparent;
    border: 5px solid currentColor;
    border-radius: 0.125em;
    overflow: hidden;
    cursor: pointer;
    box-shadow: 10px 10px 5px red;
}

.ripple-btn::after{
    content: ' ';
    position: absolute;
    top:var(--y);
    left:var(--x);
    transform: translate(-50%, -50%) scale(0);
    width: 200%;
    display: block;
    z-index: -1;
    aspect-ratio: 1/1;
    border-radius: 50%;
    background-color: red;
    opacity: .35;
    transition: transform .5s;
}

.ripple-animation::after{
    animation: ani 500ms;
}

@keyframes ani {
    0%{
        transform: translate(-50%, -50%) scale(0);
        opacity: 0.5;
    }
    100%{
        transform: translate(-50%, -50%) scale(1);
        opacity: 0;
    }
}

script.js

const buttons = document.querySelectorAll('.ripple-btn')
buttons.forEach(btn => {
    btn.addEventListener("click", (e) => ripple(e, btn))
})


function ripple(event, element) {
    let posX = event.offsetX;
    let posY = event.offsetY;
   
    element.style.setProperty("--x", `${posX}px`)
    element.style.setProperty("--y", `${posY}px`)

    element.classList.add('ripple-animation')
    element.addEventListener("animationend", () => {
        element.classList.remove("ripple-animation")
    }, {once:true})
   
}

output:
