HTML5中继名称=“视口”无法正常工作
要解决HTML5元视口的问题，可以进行以下任一修复：
<meta name = "viewport" content = "user-scalable = no, initial-scale = 1, maximum-scale = 1, minimum-scale = 1, width = 400, height = device-height, target-densitydpi=medium-dpi" />
您也可以尝试以下操作：
<meta name = "viewport" content = "width=device-width, initial-scale = 1;"/>
假设您的网站宽度为100px，则不会显示整个页面，
initial-scale = 1
