This time I will show you how to use H5 to add a zoom-disable function, and what are the precautions for using H5 to add a zoom-disable function. The following is a practical case, let's take a look.

The following piece of code introduces to you

html5Add the function of prohibiting scaling. The specific code is as follows:

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no, target-densitydpi=device-dpi" />

ps: Prohibit Html5 from scaling the screen page on mobile phones

I recently tested HTML5 pages and found that by default, users are allowed to zoom in and out of the page, or double-click on the screen to zoom in or out. That is equivalent to setting it like this

<meta name="viewport" content="width=device-width, initial-scale=1.0 user-scalable=yes" />

If you want to prohibit this situation, just modify the corresponding parameters

<meta content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0;" name="viewport" />
