<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title></title>
    </head>
    <body>
        <div id="box-1" class="box">1</div>
        <div id="box-2" class="box">2</div>
        <div id="box-3" class="box">3</div>
        <div id="box-4" class="box">4</div>
        <div id="box-5" class="box">5</div>
    </body>
</html>

<style type="text/css">
    * {
        margin: 0;
        padding: 0;
    }

    body {
        width: 100vw;
        height: 100vh;
    }

    .box {
        width: 200px;
        height: 200px;
        background-color: red;
        position: absolute;
    }

    #box-1 {
        top: 0;
        left: 0;
    }

    #box-2 {
        top: 0;
        right: 0;
    }

    #box-3 {
        bottom: 0;
        left: 0;
    }

    #box-4 {
        bottom: 0;
        right: 0;
    }

    #box-5 {
        top: 50%;
        left: 50%;
        transform: translate(-50%, -50%);
    }
</style>

边上4个 position:absolute;设置left,top等值
中间 margin:0 auto;
