您将获得默认视口(viewport)设置。请参阅Apple iOS docs - meta tag并搜索“视口(viewport)”。

Property Description

width The width of the viewport in pixels. The default is 980. The range is from 200 to 10,000. You can also set this property to the constants described in “number.”Available in iOS 1.0 and later.

要获取设备宽度，请按照文档:

For example, to set the viewport width to the width of the device, add this to your HTML file:

<meta name="viewport" content="width=device-width" />
