实现两个div，等宽，随body宽度变化，中间有空隙10px

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
    <style type="text/css">
        html,
        body {
            margin: 0;
            padding: 0;
            width: 100%;
        }

 

        #left,
        #right {
            height: 100px;
            background-color: #f00;
            width: calc(50% - 5px);
        }

 

        #left {
            float: left;
        }

 

        #right {
            float: right;
        }
    </style>
</head>
<body>
    <div id="left"></div>
    <div id="right"></div>
</body>
</html>
