瀏覽器窗口的一些問(wèn)題
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<style type="text/css">
*{
??? margin:0;padding:0;}?? ?
</style>
</head>
<body>
<script type="text/javascript">
document.write(document.body.clientWidth);
document.write('?? ');
document.write(document.body.clientHeight);
</script>
</body>
</html>
為什么這個(gè)一直都是
document.write(document.body.clientHeight);
18像素或者22像素？

你body里面沒(méi)有東西，計(jì)算的是body的高度。
