Modular built-ins let you split your Sass code into smaller, reusable modules. This makes it easier to maintain, update, and understand your styles as your project grows.
The @use rule loads a Sass module and makes its variables, mixins, and functions available with a namespace. This is the modern modular approach.
Namespaces in modular Sass apply to variables, functions, and mixins to avoid naming conflicts. They do not change the actual CSS selectors output.
Creating separate modules for layout styles and including them with @use keeps code organized, reusable, and easier to maintain.
Modular Sass lets you create reusable style modules for accessibility features like focus outlines and ARIA attribute styling. This ensures consistent and maintainable accessibility support.
