Add these words to the
which
Width=device-width: Indicates width is the width of the device screen
initial-scale=1.0: Indicates the initial zoom ratio
minimum-scale=0.5: Represents the minimum zoom ratio
Maximum-scale=2.0: Represents the maximum zoom ratio
User-scalable=yes: Indicates whether the user can adjust the zoom ratio
If you want to open a webpage, it is automatically displayed at the original scale, and the user is not allowed to modify it:
<meta name= "viewport" content= "Width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, User-scalable=no "/>
In this way, you can set the width of some of the images, such as header banners, to style= "width:100%", and the entire page looks like a full screen on the device.
