How to change the bootstrap primary color?

Question

Is it possible to change the bootstrap primary color to match to the brand color? I am using bootswatch's paper theme in my case.

Answer 1

Bootstrap 5.3 (update 2023)

Here's an example using an existing color variable ($orange).

// required to get $orange variable
@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 (update 2021)

The SASS override method is still the same for Bootstrap 5. If you're not referencing any existing Bootstrap variables to set the the new colors, you just need to set the theme variable(s) and @import bootstrap

$primary: rebeccapurple;

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

https://codeply.com/p/iauLPArGqE

Bootstrap 4*

To change the primary, or any of the theme colors in Bootstrap 4 SASS, set the appropriate variables before importing bootstrap.scss. This allows your custom scss to override the !default values...

$primary: purple;
$danger: red;

@import "bootstrap";

Demo: https://codeply.com/go/f5OmhIdre3

---

In some cases, you may want to set a new color from another existing Bootstrap variable. For this @import the functions and variables first so they can be referenced in the customizations...

/* import the necessary Bootstrap files */
@import "bootstrap/functions";
@import "bootstrap/variables";

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

/* finally, import Bootstrap */
@import "bootstrap";

---

It's also possible to change the primary color with CSS only but it requires a lot of additional CSS since there are many -primary variations (btn-primary, alert-primary, bg-primary, text-primary, table-primary, border-primary, etc...) and some of these classes have slight colors variations on borders, hover, and active states. Therefore, if you must use CSS it's better to use target one component such as changing the primary button color.

Answer 2

Bootstrap 5.2. update

If you are working with SCSS and you would like to modify colors you should add maps to your SCSS file.

@import "../../node_modules/bootstrap/scss/functions";
@import "../../node_modules/bootstrap/scss/variables";
@import "../../node_modules/bootstrap/scss/maps"; // MAPS FILE - SINCE 5.2

and then:

$custom-colors: (
        "white": $white, // your colours
);
$theme-colors: map-merge($theme-colors, $custom-colors);
$theme-colors-rgb: map-loop($theme-colors, to-rgb, "$value");
$utilities-colors: map-merge($utilities-colors, $theme-colors-rgb);
$utilities-text-colors: map-loop($utilities-colors, rgba-css-var, "$key", "text");
$utilities-bg-colors: map-loop($utilities-colors, rgba-css-var, "$key", "bg");

and finally:

@import "../../node_modules/bootstrap/scss/mixins";
@import "../../node_modules/bootstrap/scss/utilities";

and the rest.

Answer 3

There are two ways you can go to

http://getbootstrap.com/customize/

And change the color in this adjustments and download the bootstrap customized.

Or you can use sass with this version https://github.com/twbs/bootstrap-sass and import in your sass assets/stylesheets/_bootstrap.scss but before import this you can change the defaults variable colors

//== Colors
//
//## Gray and brand colors for use across Bootstrap.

$gray-base:              #000 !default;
$gray-darker:            lighten($gray-base, 13.5%) !default; // #222
$gray-dark:              lighten($gray-base, 20%) !default;   // #333
$gray:                   lighten($gray-base, 33.5%) !default; // #555
$gray-light:             lighten($gray-base, 46.7%) !default; // #777
$gray-lighter:           lighten($gray-base, 93.5%) !default; // #eee

$brand-primary:         darken(#428bca, 6.5%) !default; // #337ab7
$brand-success:         #5cb85c !default;
$brand-info:            #5bc0de !default;
$brand-warning:         #f0ad4e !default;
$brand-danger:          #d9534f !default;


//== Scaffolding
//
//## Settings for some of the most global styles.

//** Background color for `<body>`.
$body-bg:               #fff !default;
//** Global text color on `<body>`.
$text-color:            $gray-dark !default;

//** Global textual link color.
$link-color:            $brand-primary !default;
//** Link hover color set via `darken()` function.
$link-hover-color:      darken($link-color, 15%) !default;
//** Link hover decoration.
$link-hover-decoration: underline !default;

And compile the result

Answer 4

Any element with 'primary' tag has the color @brand-primary. One of the options to change it is adding a customized css file like below:

.my-primary{
  color: lightYellow ;
  background-color: red;
}

.my-primary:focus, .my-primary:hover{
  color: yellow ;
  background-color: darkRed;
}

a.navbar-brand {
  color: lightYellow ;
}

.navbar-brand:hover{
  color: yellow;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css" rel="stylesheet"/>

<div class="container">
  <br>
  <nav class="navbar navbar-dark bg-primary mb-3">
    <div class="container">
      <a class="navbar-brand" href="/">Default (navbar-dark  bg-primary)</a>
    </div>
  </nav>
  <button type="button" class="btn btn-primary">Default (btn btn-primary)</button>
  </div>


<br>

<div class="container">
  <nav class="navbar my-primary mb-3">
    <div class="container">
      <a class="navbar-brand" href="/">Customized (my-primary)</a>
    </div>
  </nav>
  <button type="button" class="btn my-primary">Customized (btn my-primary)</button>
  </div>

$primary: #00adef;

$theme-colors: (
  "primary":    $primary,
);

Bootstrap 5

For bootstrap 5 you can just go to you main scss file and add:

$primary: #d93eba;
$body-bg: #fff;
$secondary: #8300d9;

or whatever changes you wanna make...

And don't forget to import bootstrap right after.

Your final main.scss file should look like this:

$primary: #d93eba;
$body-bg: #fff;
$secondary: #8300d9;


@import "~node_modules/bootstrap/scss/bootstrap";

Bootstrap 4 rules

Most of the answers here are more or less correct, but all of them with some issues (for me). So, finally, googleing I found the correct procedure, as stated in the dedicated bootstrap doc: https://getbootstrap.com/docs/4.0/getting-started/theming/.

Let's assume bootstrap is installed in node_modules/bootstrap.

A. Create your your_bootstrap.scss file:

@import "your_variables_theme";    // here your variables

// mandatory imports from bootstrap src
@import "../node_modules/bootstrap/scss/functions";
@import "../node_modules/bootstrap/scss/variables"; // here bootstrap variables
@import "../node_modules/bootstrap/scss/mixins";

// optional imports from bootstrap (do not import 'bootstrap.scss'!)
@import "../node_modules/bootstrap/scss/root";
@import "../node_modules/bootstrap/scss/reboot";
@import "../node_modules/bootstrap/scss/type";
etc...

B. In the same folder, create the _your_variables_theme.scss file.

C. Customize the bootstrap variables in _your_variables_theme.scss file following this rules:

Copy and paste variables from _variables.scss as needed, modify their values, and remove the !default flag. If a variable has already been assigned, then it won’t be re-assigned by the default values in Bootstrap.

Variable overrides within the same Sass file can come before or after the default variables. However, when overriding across Sass files, your overrides must come before you import Bootstrap’s Sass files.

Default variables are available in node_modules/bootstrap/scss/variables.scss.

Answer 8

Bootstrap 4

This is what worked for me:

I created my own _custom_theme.scss file with content similar to:

/* To simplify I'm only changing the primary color */
$theme-colors: ( "primary":#ffd800);

Added it to the top of the file bootstrap.scss and recompiled (In my case I had it in a folder called !scss)

@import "../../../!scss/_custom_theme.scss";
@import "functions";
@import "variables";
@import "mixins";

Answer 9

I've created this tool: https://lingtalfi.com/bootstrap4-color-generator, you simply put primary in the first field, then choose your color, and click generate.

Then copy the generated scss or css code, and paste it in a file named my-colors.scss or my-colors.css (or whatever name you want).

Once you compile the scss into css, you can include that css file AFTER the bootstrap CSS and you'll be good to go.

The whole process takes about 10 seconds if you get the gist of it, provided that the my-colors.scss file is already created and included in your head tag.

Note: this tool can be used to override bootstrap's default colors (primary, secondary, danger, ...), but you can also create custom colors if you want (blue, green, ternary, ...).

Note2: this tool was made to work with bootstrap 4 (i.e. not any subsequent version for now).

Answer 10

This might be a little bit old question, but I want to share the best way I found to customize bootstrap. There's an online tool called bootstrap.build https://bootstrap.build/app. It works great and no installation or building tools setup required!

Answer 11

The correct way to change the default primary colour in Bootstrap 4.x using SASS, or any other colours like secondary, success and so on.

Create the following SASS file and import Bootstrap SASS as indicated:

// (Required) Import Bootstrap
@import "bootstrap/functions";
@import "bootstrap/variables";
@import "bootstrap/mixins";

$primary: blue;
$secondary: green;
$my-color: red;

$theme-colors: (
  primary: $primary,
  secondary: $secondary,
  my-color: $my-color
);

// Add below your SASS or CSS code

// (Required) Import Bootstrap
@import "bootstrap/bootstrap";

Answer 12

• You cannot change the color in cdn file.
• Download the bootstrap file.
• Search For bootstrap.css file.
• open this(bootstrsap.css) file and search for 'primary'.
• change it to the colour you desire.

Answer 13

This is a very easy solution.

<h4 class="card-header bg-dark text-white text-center">Renew your Membership</h4>

replace the class bg-dark, with bg-custom.

In CSS

.bg-custom {
  background-color: red;
}

Answer 14

Since Bootstrap 4 you can easily change the primary color of your Bootstrap by downloading a simple CSS file on BootstrapColor.net. You don't need to know SASS and the CSS file is ready to use for your website. You can choose the color you want like blue, indigo, purple, pink, red, orange, yellow, green, teal or cyan color.

Answer 15

Using SaSS
change the brand color

$brand-primary:#some-color;

this will change the primary color accross all UI.

Using css-
suppose you want to change button primary color.So

btn.primary{
  background:#some-color;
}

search the element and add a new css/sass rule in a new file and attach it after u load the bootstrap css.

Answer 16

Yes, I'd suggest opening up the .css file, inspect the page and find the color code you want to change and Find All and Replace (depending on your text editor) to the color you want. Do that with all the colors you want to change
