How can I create a custom Bootstrap theme using Sass variables?
Asked on Feb 11, 2026
Answer
Creating a custom Bootstrap theme using Sass variables allows you to customize the look and feel of your Bootstrap-based project efficiently. You can override Bootstrap's default variables by creating a custom Sass file.
<!-- BEGIN COPY / PASTE -->
// Step 1: Import Bootstrap's functions
@import 'node_modules/bootstrap/scss/functions';
// Step 2: Override default Bootstrap variables
$primary: #ff5733;
$font-family-base: 'Arial, sans-serif';
// Step 3: Import Bootstrap's rest of the files
@import 'node_modules/bootstrap/scss/bootstrap';
<!-- END COPY / PASTE -->Additional Comment:
