Bootstrap classes .pe-none and .pe-auto classes prevents and enabling of element interactions as demostrated in the following example.
Example
You can edit and try running this code using Edit & Run option.
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap - Interactions</title>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet">
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"></script>
</head>
<body>
<p>Use the "pe-none" class to make the <a href="#" class="pe-none" tabindex="-1" aria-disabled="true">link</a> inactive.</p>
<p>Use the "pe-auto" class to make the <a href="#" class="pe-auto">link</a> active.</p>
<p class="pe-none"><a href="#" tabindex="-1" aria-disabled="true">This link </a> is not active due to the inherited pointer-events property. Now, <a href="#" class="pe-auto">This link</a> is an active.</p>
</body>
</html>
-
The .pe-none class, along with the pointer-events CSS property it applies, is designed to disable interactions specifically with a pointer, such as a mouse, stylus, or touch input. By default, links, and controls with .pe-none remain functional and accessible for keyboard users.
-
In order to achieve full neutralization for keyboard users, additional attributes can be included for keyboard users. These attributes may include tabindex=”-1″ to prevent keyboard focus, aria-disabled=”true” to indicate their disabled state to assistive technologies, and JavaScript could also be utilized to fully prevent any action on them.
If possible, it can be done in a simpler way:
-
For form controls: You can add the disabled attribute in the HTML.
-
For links: Remove the “href” attribute from links, effectively making them non-interactive or placeholder elements.
