Text Selection

Use user-select-all, user-select-auto, or user-select-none class to the content which is selected when the user interacts with it.

This paragraph will be entirely selected when clicked by the user.

This paragraph has default select behavior.

This paragraph will not be selectable when clicked by the user.

<!-- Text Selection -->
<p class="user-select-all">This paragraph will be entirely selected when clicked by the user.</p>

<p class="user-select-auto">This paragraph has default select behavior.</p>

<p class="user-select-none mb-0">This paragraph will not be selectable when clicked by the user.</p>

Pointer Events

Use pe-none class to prevent and pe-auto class to add element interactions respectively.

This link can not be clicked.

This link can be clicked (this is default behavior).

This link can not be clicked because the pointer-events property is inherited from its parent. However, this link has a pe-auto class and can be clicked.

<!-- Pointer events -->
<p><a href="#" class="text-success pe-none" tabindex="-1" aria-disabled="true">This link</a> can not be clicked.</p>

<p><a href="#" class="text-success pe-auto">This link</a> can be clicked (this is default behavior).</p>

<p class="pe-none mb-0"><a href="#" class="text-success" tabindex="-1" aria-disabled="true">This link</a> can not be clicked because the <code>pointer-events</code> property is inherited from its parent.
