user-select
The user-select
CSS property controls whether the user can select text. This doesn't have any effect on content loaded as part of a browser's user interface (its chrome), except in textboxes.
/* Keyword values */
user-select: none;
user-select: auto;
user-select: text;
user-select: contain;
user-select: all;
/* Global values */
user-select: inherit;
user-select: initial;
user-select: revert;
user-select: unset;
/* Mozilla-specific values */
-moz-user-select: none;
-moz-user-select: text;
-moz-user-select: all;
/* WebKit-specific values */
-webkit-user-select: none;
-webkit-user-select: text;
-webkit-user-select: all; /* Doesn't work in Safari; use only
"none" or "text", or else it will
allow typing in the <html> container */
/* Microsoft-specific values */
-ms-user-select: none;
-ms-user-select: text;
-ms-user-select: element;
Note: user-select
is not an inherited property, though the initial auto
value makes it behave like it is inherited most of the time. WebKit/Chromium-based browsers do implement the property as inherited, which violates the behavior described in the spec, and this will bring some issues. Until now, Chromium chooses to fix the issues, make the final behavior meets the specifications.
