Sass

Sass

Sass customization lets developers change Bootstrap\'s source variables and maps before the framework CSS is generated.

Core concept

Explain the source-to-output process, variable overrides, Sass maps, imports, compilation, and why generated CSS should not be edited manually.

Using it in a real interface

Show a custom primary color compiled through Sass and explain how the generated framework then contains the chosen value. Mention that the exact import order matters because later source files may depend on earlier variables.

Implementation notes

Keep the Bootstrap source version controlled through package management and keep custom Sass in the application\'s source tree. This makes upgrades and rebuilds repeatable.
