As a beginner, I saw JQ in the tag of the poster’s question, so I wrote it with great interest. In fact, the CSS3 properties upstairs are really good!

<!DOCTYPE html>
<html>

<head>
    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <title>两边展开</title>
    <link rel="stylesheet" href="">
    <style>
    .content {
        width: 100px;
        height: 100px;
        position: relative;
        overflow: hidden;
    }
    
    .content p {
        position: absolute;
        width: 49px;
        height: 100px;
    }
    
    .left {
        left: 0;
        background-color: black;
        margin-right: 2px;
    }
    
    .right {
        background-color: black;
        right: 0;
    }
    </style>
</head>

<body>
    <p class="content">
        <p class="left"></p>
        <p class="right"></p>
    </p>
    <script src="js/jquery-1.12.0.min.js"></script>
    <script>
    $(function() {
        $(".content").click(function() {
            $(".left").animate({
                left: "-49px"
            }, 1000);
            $(".right").animate({
                right: "-49px"
            }, 1000)
        })
    })
    </script>
</body>

Use the translateX(n) attribute, see the document below
