--- layout: docs title: Interactions description: Utility classes that change how users interact with contents of a website. group: utilities toc: false --- ## Text selection Change the way in which the content is selected when the user interacts with it. {{< example >}} <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">This paragraph will not be selectable when clicked by the user.</p> {{< /example >}} ## Pointer events Bootstrap provides `.pe-none` and `.pe-auto` classes to prevent or add element interactions. {{< example >}} <p><a href="#" class="pe-none" tabindex="-1" aria-disabled="true">This link</a> can not be clicked.</p> <p><a href="#" class="pe-auto">This link</a> can be clicked (this is default behavior).</p> <p class="pe-none"><a href="#" tabindex="-1" aria-disabled="true">This link</a> can not be clicked because the <code>pointer-events</code> property is inherited from its parent. However, <a href="#" class="pe-auto">this link</a> has a <code>pe-auto</code> class and can be clicked.</p> {{< /example >}} The `.pe-none` class (and the `pointer-events` CSS property it sets) only prevents interactions with a pointer (mouse, stylus, touch). Links and controls with `.pe-none` are, by default, still focusable and actionable for keyboard users. To ensure that they are completely neutralized even for keyboard users, you may need to add further attributes such as `tabindex="-1"` (to prevent them from receiving keyboard focus) and `aria-disabled="true"` (to convey the fact they are effectively disabled to assistive technologies), and possibly use JavaScript to completely prevent them from being actionable. If possible, the simpler solution is: - For form controls, add the `disabled` HTML attribute. - For links, remove the `href` attribute, making it a non-interactive anchor or placeholder link. ## Sass ### Utilities API Interaction utilities are declared in our utilities API in `scss/_utilities.scss`.
