Learn @use and @import rule and directive SASS|SCSS
In this tutorial, we are going to learn @import and @use features with examples and the difference between with.
@import directive in SASS
@import is used to import CSS and sass styles As you know SASS is an open-source preprocessor language used in applications @import directive rule @import in CSS is used to import styles from one file into other CSS styles, SASS also works the same way, Only difference is CSS makes an extra HTTP call to imports it, SASS will not make an extra call.
Another difference is SASS imports other features mixins, partials, and all other features.
The advantages of this approach are reusable and not repeated code Syntax
@import "filename"
if you have all your colors-related styles in colors.scss, then import into main.scss
@import is used in both to include style sheet files into other style sheets.
