1. Use the meta tag: viewport
A commonly used method for H5 mobile page adaptation. Theoretically speaking, using this tag can adapt to all screen sizes, but each device has different requirements. The different interpretation methods and support levels of tags result in incompatibility with all browsers or systems.
viewport is the visible area of the user web page. Translated into Chinese, it can be called "view area".
Mobile browsers place the page in a virtual "window" (viewport). Usually this virtual "window" (viewport) is wider than the screen, so that each web page does not need to be squeezed into a small size. In a window (which would break the layout of webpages that are not optimized for mobile browsers), users can pan and zoom to see different parts of the webpage.
Viewport tag and its attributes:
<meta name="viewport" content="width=device-width,initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no"/>
Detailed introduction of each attribute:
Attribute name | Value | Description |
---|---|---|
Positive integer or device-width | defines the width of the viewport, The unit is pixels | |
Positive integer or device-height | defines the height of the viewport, the unit is pixels, generally not used | |
[0.0-10.0] | Define the initial scaling value | |
[0.0-10.0] | Define the minimum scaling, it must be less than or equal to the maximum-scale setting | |
[ 0.0-10.0] | Define the maximum zoom ratio, which must be greater than or equal to the minimum-scale setting | |
yes/no | Define whether to allow users to manually zoom the page, the default value is yes |
