<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Document</title>
    <style>
        *{
            margin: 0;
            padding: 0;
        }
        .box {
            display: flex;
            justify-content: center;
            align-items: center;
        }
        span {
            position: relative;
            margin: 50px auto;
            border: 1px solid;
        }
        span[aria-label]:hover:after {
            content: attr(aria-label);
            position: absolute;
            bottom: -30px;
            left: 0;

            width: 100%;
        }
    </style>
