Shades and Opacity

Bootstrap 5 allows you to adjust the opacity of colors using utility classes. This feature is especially useful for overlays and subtle effects.

Opacity Classes

Example: Adjusting Opacity

<div class="bg-primary text-white p-3 opacity-75">75% Opacity</div>
<div class="bg-danger text-white p-3 opacity-50">50% Opacity</div>
<div class="bg-warning text-dark p-3 opacity-25">25% Opacity</div>

Customizing Bootstrap Colors

You can customize Bootstrap’s colors using Sass. Modify the default variables to match your brand’s color palette.

Example: Custom Sass Variables

$primary: #4CAF50;
$secondary: #FFC107;
$success: #8BC34A;
$danger: #F44336;
$warning: #FF9800;
$info: #03A9F4;

@import "bootstrap";

After defining your custom colors, compile the Sass file, and the changes will be applied globally.
