Using HTML, JavaScript and CSS it is possible to remove text selection in following way.
1. Custom back compatible example
This approach removes text selecting (and not only) option from element by adding:
- specific class (
.disable-selectiondefined in example code) unselectable="on"attribute - required by IE < 10 and Opera < 15onselectstart="return false;"- alternative solution for Internet Explorer
Notes:
- some browsers still does not support
user-selectproperty (Can I use link here), so it is necessary to use prefixes for full capability.user-selectproprty is not part of standard - it has working draft status for CSS4.
// ONLINE-RUNNER:browser;
<!doctype html>
<html>
<head>
<style>
.disable-selection {
-webkit-touch-callout: none; /* iOS Safari */
-webkit-user-select: none; /* Safari */
-khtml-user-select: none; /* Konqueror HTML */
-moz-user-select: none; /* Firefox in the past (old versions) */
-ms-user-select: none; /* Internet Explorer (>=10) / Edge */
user-select: none; /* Currently supported: */
/* Chrome, Opera and Firefox */
}
div {
margin: 10px;
padding: 20px;
}
</style>
</head>
<body>
<div class="disable-selection"
style="background: silver;"
unselectable="on"
onselectstart="return false;">
This text is not selectable ...
</div>
<div style="background: gold;">
This text is selectable ...
</div>
</body>
</html>
