您好。我看了那个文章。

可是我还是有疑问。

我手机是1280*720 就是说我手机宽720像素。
可是我把网页设置成720px网页却超出了屏幕范围div{width:720px;}
请问是为什么

我把div{width:360px;}网页就不超宽。请问这是怎么回事???

我总有可能给div设置宽度啊!!!

按百分比定位宽度。
刚才才发现你发了两篇,我给回复到 html5那个版里了

<!DOCTYPE html><html><head><meta name="viewport" content="width=device-width,initial-scale=1.0" /><meta charset="UTF-8" /><style type="text/css">*{margin:0px;}div{    width:700px;    height:200px;    border:solid 1px #000000;}</style></head><body><div>123</div></body></html> 



因为你设置了 width=device-width

1280*720 的手机  应该是高清屏吧 像素点是这样  实际是 一半

meta改一下试试

content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no"
