user-select
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Theuser-select
CSSproperty controls whether the user can select text. This doesn't have any effect on content loaded as part of a browser's user interface (itschrome), except in textboxes.

Syntax
/* Keyword values */
user-select: none;
user-select: auto;
user-select: text;
user-select: all;
/* Global values */
user-select: inherit;
user-select: initial;
user-select: revert;
user-select: revert-layer;
user-select: unset;
Note:user-select
is not an inherited property, though the initialauto
value makes it behave like it is inherited most of the time. WebKit/Chromium-based browsersdoimplement the property as inherited, which violates the behavior described in the spec, and this will bring some issues. Until now, Chromium has chosen tofix the issuesto make the final behavior meet the specifications.
