Customizing SASS

Customizing the Frest's SASS is super easy. Every SASS variable in Frest includes the !default flag allowing you to override the variable's default value in your own SASS without modifying either Bootstrap or Frest's source code.

Changing variables

Using _custom-variables/ folder's scss files, you can easily override light/dark style variables for bootstrap, custom component, libraries and pages. Copy and paste variables 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.

Now, you might have more questions like below:

How can I override Bootstrap variable(s)?

To change bootstrap color variable other than Primary, you need to do below changes to scss/_custom-variables/_bootstrap-extended.scss file.

If you want to update color for dark layout, then you can add same variable to scss/_custom-variables/_bootstrap-extended-dark.scss file.

$success: #009900 !default;

How can I override custom components variable(s)?

To change custom components variables like menu width, you need to do below changes to scss/_custom-variables/_components.scss file

If you want to update color for dark layout, then you can add same variable to scss/_custom-variables/_components-dark.scss file.

$menu-width: 14rem !default;

How can I override third-party library's variable(s)?

$flatpickr-width: 20rem;

How can I override pages variable(s)?

$calender-sidebar-width: 20rem;

Where should I write my custom scss?

To write your custom style create style.scss file inside scss/ folder and write your styes in that file. Just don't forget to include it in your HTML file.


By default, stylesheets within src/libs/ and src/scss/pages/ directories include all available support, such as rtl support; light and dark styles. If you don't want to use them, it's highly recommended to disable unwanted support. It will decrease the size of compiled stylesheets.

Set appropriate variables to false in the src/scss/_custom-variables/_support.scss, recompile sources.

For example, if you don't need to include RTL support, the src/scss/_custom-variables/_support.scss file will look like this:

$enable-light-style: true;
$enable-dark-style: true;
$enable-rtl-support: false;


How can I change theme primary color?

Frest is theme based admin template. So we suggest you to update primary color theme wise from scss/theme-*.scss file.

If you are familiar with SCSS (Recommended method), you can easily change theme colors by changing variable value. For example, if you want to update default theme of the template, open scss/theme-default.scss file

$primary-color: #757575;

To change the primary color throughout your entire project. For Light layout update $primary in scss/_custom-variables/_bootstrap-extended.scss file. For Dark Layout update $primary in scss/_custom-variables/_bootstrap-extended-dark.scss

$primary: #757575;

Find all the custom variable css files at below path:

├── 📂 scss                                       > Core SCSS
│   ├── 📂 _custom-variables                        > Custom variables (use this files to override variables)
│   │   ├── 📄 _bootstrap-extended.scss               > To override Bootstrap extended variable
│   │   ├── 📄 _bootstrap-extended-dark.scss          > To override Bootstrap extended dark variable
│   │   ├── 📄 _components.scss                       > To override Custom components variable

│   │   └── 📄 support.scss                           > To override Support variables

How can I create new theme (own theme)?

Frest admin template comes with unique feature to create custom theme. So user can easily integrate template with their own choice & requirements.

To create custom theme, you need to create scss files that contains variables, custom scss and primary color variable of the theme. It's required to set $primary-color variable to use base primary color for custom theme.

Let's say, if you want to create your own custom theme named as raspberry, follow steps below.

  • First of all, create custom theme scss files, like theme-raspberry.scss and theme-raspberry-dark.scss inside scss/ folder.
  • To apply custom theme, replace custom css files with other included theme-*.css files.
  • To add custom theme style , please Read more.
  • To add custom theme to customizer, please Read more.

Now, How to add variables, styles & mixins to theme scss file.

  • To use declared variables & mixins, Theme requires to include library, pages, variable files.
  • Theme requires primary color variable to update color as require. So need to add $primary-color variable with basic includes like below
  • // Component variables include
    @import './_components/include';
    @import './_theme/common';
    @import './_theme/libs';
    @import './_theme/pages';
    $primary-color: #e30b5c;
    // To update color to custom theme's primary color
    @include template-common-theme($primary-color);
    @include template-libs-theme($primary-color);
    @include template-pages-theme($primary-color);
  • After applying primary color for each library, components & pages, To update navbar, You can add custom style after including mixin as below :
  • @include template-navbar-style('.bg-navbar-theme', BACKGROUND_COLOR, $color: TEXT_COLOR, $active-color: ACTIVE_TEXT_COLOR, $border: BORDER_COLOR);
  • To update menu, You can add custom style after including mixin as below :
  • @include template-menu-style('.bg-menu-theme',BACKGROUND_COLOR, $color: TEXT_COLOR, $active-color: ACTIVE_TEXT_COLOR, $border: BORDER_COLOR, $active-bg: ACTIVE_BACKGROUND_COLOR);
  • To update footer, You can add custom style after including mixin as below :
  • @include template-footer-style('.bg-footer-theme', BACKGROUND_COLOR, $color: TEXT_COLOR, $active-color: ACTIVE_TEXT_COLOR, $border: BORDER_COLOR);
  • You can also add style that should work for custom theme only.
  • That's All!!
