This time I will bring you H5 mobile page scaling. What are the precautions for H5 mobile page scaling? Here is a practical case, let’s take a look.

Usually when writing HTML5 mobile page, we will find that the proportion of elements displayed on the page is incorrect, then what we need to add at this time is:

<meta name="viewport" content="width=device-width,initial-scale=1">

<meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=0.5, maximum-scale=2.0, user-scalable=yes" />

Then let’s explain this sentence:

viewport: represents the display window;

width=device-width,initial-scale= 1.0: Indicates that the width of the display window is equal to the screen width of the device, initial-scale=1.0, that is, the initial scaling ratio is 1.0;

minimum-scale: Indicates the minimum scaling ratio allowed

maximum: Indicates the maximum scaling ratio allowed

user-scalable: Indicates whether the user is allowed to zoom the page, the value can be yes or no

Instance problem situation ：

## Phenomenon:

When the user clicks the input box to edit text on the mobile page, the page will automatically be enlarged

Solution:

Insert

<meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0" />

in the header<head

> tag of the page or do not allow users to zoom the page user-scalable=no
