在一个html页面中，只有一个div,想是div充满全屏，常规的想法是设置高度宽度为100% ，代码如下：<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <body bgcolor="red"> <div id="bg" style="width:100%;height:100%;"> </div> </body> </html> ??但是这样的话，div四周都会有边距，并没充满全屏。解决办法如下：<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <style> html,body{ margin:0px; height:100%; } #bg{ width:100%; height:100%; MARGIN: 0px auto; background-color:blue; } </style> <body bgcolor="red"> <div id="bg"> </div> </body> </html> ??????
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<style type="text/css">

.ni{ width:100px; height:100px; background:#F00; position:fixed; top:50%; left:50%; margin-top:-50px; margin-top:-50px; z-index:15;}
