How Can I Customize Bootstrap's Primary Color in Different Versions?

Customizing Bootstrap Primary Color

Bootstrap, a popular front-end framework, grants users extensive customization options. One common modification is changing the primary color to align with a brand's identity. This article explores how to achieve this in various versions of Bootstrap.

Bootstrap 5.3

Bootstrap 5.3 introduces a more straightforward approach. Using SASS, you can set the $primary variable to your desired color. Here's an example:

@import "functions";
@import "variables";

$primary: $orange; // set the $primary variable

// merge with existing $theme-colors map
$theme-colors: map-merge($theme-colors, (
  "primary": $primary
));

// set changes
@import "bootstrap";

Bootstrap 5

In Bootstrap 5, the method is similar. However, if you're not referencing existing Bootstrap variables to set the new colors, simply set the $primary variable and import Bootstrap:

$primary: rebeccapurple;

@import "bootstrap"; // use full path to bootstrap.scss

Bootstrap 4

For Bootstrap 4, the customization process involves setting the appropriate variables before importing Bootstrap. For instance, to change the primary color:

$primary: purple;
$danger: red;

@import "bootstrap";

Note: In certain scenarios, you may wish to set a new color based on an existing Bootstrap variable. To do this, import the functions and variables files beforehand:

@import "bootstrap/functions";
@import "bootstrap/variables";

$theme-colors: (
  primary: $purple
);

@import "bootstrap";

Additional Considerations

In some cases, changing the primary color via CSS alone may be preferable. However, this approach requires more CSS due to the numerous "-primary" variations, each with potential variations on borders, hover, and active states. Therefore, using CSS to modify a specific component (e.g., buttons) is more practical.
