The user-select property is a new property added by css3 and is used to set whether users can select Chinese text.

Grammar.

User-select:none | text | all | element

Default value: text

Scope of application: all elements except replacement elements

Value description

None: text cannot be selected

Text: you can select text

All: can be selected when all content as a whole. If you double-click or click a child element in the context, the selected section will be the highest ancestor element backtracking with that child element.

Element: text can be selected, but the selection range is constrained by element boundaries

Description

1. IE6-9 does not support this attribute, but supports the use of the tag attribute onselectstart= "returnfalse;" to achieve the user-select:none effect; Safari and Chrome also support this tag attribute

2. This attribute is still not supported until Opera12.5, but like IE6-9, the private tag attribute unselectable= "on" is also supported to achieve the user-select:none effect; another value of unselectable is off.

3. In addition to Chrome and * Safari, in other browsers, if the text is set to-ms-user-select:none;, users will not be able to start selecting text in the text block.
