Going back to the root level with @at-root in SCSS

The @at-root takes the selector from its current nesting scope and moves that selector to the root of the file. This means that the following SCSS code:

.user {
    color: blue;
    @at-root .info {
        color: red;
    }
}

Will be compiled to:

.user { color: blue; }
.info { color: red; }
/* insead of :
.user { color: blue; }
.user .info { color: red; } */

It is useful as it allows us to group CSS rules but not to increase the specificity of these rules, making them easier to override if needed.

And this is true even in the case of multiple nesting. It will move the @at-root declaration at the top no matter how deep the nesting goes:

.container {
    .item {
        @at-root .title {
            color: red;
        }
    }
}
/* will be compiled just to .title { color: red; } */

One small this to note is using the @at-root with media queries. We can use @at-root (without: media) and @at-root (with: media) to decide if we want to still keep the media query or not.

@media (max-width: 600px) {
   .user {
      height: 8px;
      @at-root (without: media) {
            // rules here
      }
   }
}
