Support CoreUI Development

CoreUI is an MIT-licensed open source project and is completely free to use. However, the amount of effort needed to maintain and develop new features for the project is not sustainable without proper financial backing.

You can support our Open Source software development in the following ways:

  • Buy the CoreUI PRO, and get access to PRO components, and dedicated support.
  • Became a sponsor, and get your logo on BACKERS.md/README.md files or each site of this documentation
  • Give us a star ⭐️ on Github.

Customize

Learn how to theme, customize, and extend CoreUI Bootstrap Templates with Sass, a boatload of global options.

Overview

There are multiple ways to customize CoreUI for Bootstrap. Your best path can depend on your project, the complexity of your build tools, the version of CoreUI for Bootstrap you’re using, browser support, and more.

Our two preferred methods are:

  1. You can extend our source files.
  2. You can override CoreUI’s styles.

File structure

Utilize our source Sass files to take advantage of variables, maps, mixins, and functions to help you build faster and customize your project.

Whenever possible, avoid modifying CoreUI’s core files. For Sass, that means creating your own stylesheet that imports CoreUI for Bootstrap so you can modify and extend it. Assuming you’re using a package manager like npm, you’ll have a file structure that looks like this:

your-project/
├── ...
├── node_modules/
│   └── @coreui/coreui
│       ├── js
│       └── scss
├── src
│   └── scss
│       ├── _custom.scss
│       ├── ...
│       ├── _variables.scss
│       └── ...
└── ...

Variable defaults

Every Sass variable in CoreUI for Bootstrap includes the !default flag allowing you to override the variable’s default value in your own Sass without modifying CoreUI’s source code. 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 in CoreUI.

You will find the complete list of CoreUI’s variables in node_modules/@coreui/coreui/scss/_variables.scss or node_modules/@coreui/coreui-pro/scss/_variables.scss if you use CoreUI PRO. Some variables are set to null, these variables don’t output the property unless they are overridden in your configuration. You can also find a specific component variables list in Customizing section ex. Alerts - Customizing

Here’s an example that changes the background-color and color for the <body> when importing and compiling CoreUI for Bootstrap via npm:

// _variables.scss

// Default variable overrides
$body-bg: #000;
$body-color: #111;

Custom styles and overrides

In your custom.scss, you can put custom code for CoreUI’s components or your own styles.

// _custom.scss

// Additional custom code here
.custom-component {
  border: 2px solid #222;
}
