Preface

Recently I encountered a need at work. The effect achieved is that when the collection button on the upper right side of the product image is clicked, the zoom animation is triggered, and later by searching for relevant information , I found that this effect can be achieved by using css3:@keyframes animation. Let’s take a look at the detailed introduction.

Sample code

<!DOCTYPE html>
<head>
       <style type="text/css">
        @keyframes myfirst {
            0% {
                width: 50px;
                height: 50px;
                top: 10px;
                right: 10px;
            }
            75% {
                width: 60px;
                height: 60px;
                top: 5px;
                right: 5px;
            }
            100% {
                width: 50px;
                height: 50px;
                top: 10px;
                right: 10px;
            }
        }
        .warp {
            width: 400px;
            height: 300px;
            position: relative;
            background: #ccc;
        }
        .btn {
            position: absolute;
            width: 50px;
            height: 50px;
            border:solid 3px #cc3c24;
            top: 10px;
            right: 10px;
            border-radius: 8px;
            cursor: pointer;
        }
        .btn.cur{
            animation: myfirst 0.2s;
        }
        .btn.yes{
            background: #cc3c24;
        }
    </style>
</head>
<body>
<p class="warp">
    <p class="btn"></p>
</p>
<script src="http://liuxiaofan.com/demo/js/jquery-2.1.4.min.js"></script>
<script>
   var btn = $(&#39;.btn&#39;);
    btn.click(function () {
        if( $(this).is(&#39;.yes&#39;)){
            $(this).removeClass(&#39;yes&#39;);
            $(this).removeClass(&#39;cur&#39;);
        }else{
            $(this).addClass(&#39;yes&#39;);
            $(this).addClass(&#39;cur&#39;);
        }
    });
    btn.on(&#39;webkitAnimationEnd&#39;, function () {
        $(this).removeClass(&#39;cur&#39;);
    });
</script>
</body>
