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"
