Quick Start

Using the themes is as easy as downloading a CSS file and replacing the one that comes with Bootstrap.

The themes are also available via CDN at jsDelivr.


To modify a theme or create your own, follow the steps below in your terminal. You'll need to have Git and Node installed.

  1. Download the repository: git clone https://github.com/thomaspark/bootswatch.git

  2. Install dependencies: npm install

  3. Make sure that you have grunt available in the command line. You can install grunt-cli as described on the Grunt Getting Started page.

  4. Modify variables.less and bootswatch.less in one of the theme directories, or create your own in /custom.

  5. Type grunt swatch:[theme] to build the CSS for a theme, e.g., grunt swatch:amelia for Amelia. Or type grunt swatch to build them all at once.

  6. You can run grunt to start a server, watch for any changes to the LESS files, and automatically build a theme and reload it on change. Run grunt server for just the server, and grunt watch for just the watcher.

Here are additional tips for customizing Bootstrap.


You can use the API to integrate the themes with your platform. Get:
