## CSS variables

With v5.1.1, we standardized our required `@import`s across all our CSS bundles (including `bootstrap.css`, `bootstrap-reboot.css`, and `bootstrap-grid.css`) to include `_root.scss`. This adds `:root` level CSS variables to all bundles, regardless of how many of them are used in that bundle. Ultimately Bootstrap 5 will continue to see more [CSS variables]({{< docsref "/customize/css-variables" >}}) added over time, in order to provide more real-time customization without the need to always recompile Sass. Our approach is to take our source Sass variables and transform them into CSS variables. That way, even if you don't use CSS variables, you still have all the power of Sass. **This is still in-progress and will take time to fully implement.**

Bootstrap doesn't include `color` and `background-color` utilities for every color variable, but you can generate these yourself with our [utility API]({{< docsref "/utilities/api" >}}) and our extended Sass maps added in v5.1.0.
