Using the LESS files

The usptostrap.less file uses @import to merge all the LESS files at compilation time. Based on your folder structure, dependency management system, and 3rd party libraries, usptostrap.less may need to be updated. Use Grunt, Gulp, Maven, or some other tool to compile the LESS files.

Similar to Bootstrap, the LESS files are organized by module.

  • All Bootstrap overrides are at the root of the less folder.
  • Variables are in _variables.less.
  • CSS for new modules is in the custom folder.
  • 3rd party plugin themes are in the vendor folder.

Using the CSS files

The compiled CSS file includes a themed and extended version of Bootstrap. You shouldn't include the original Bootstrap CSS in your web page. If you're going to be writing any additional CSS specific for your web page, we recommend using the LESS files instead and taking advantage of the variables when possible.
