The Sass built-in selector module: an introduction with code examples

The SASS built-in selector module is a collection of functions within the SASS language that provides tools for working with CSS selectors. It provides functions for inspecting and manipulating selectors, as well as generating new selectors.

The selector module can be used to streamline stylesheets, making them easier to manage and maintain. With its powerful features, the SASS selector module is a valuable tool for any SASS developer.

In this blog post, we will explore the SASS built-in selector module and see how it can be used with code examples.

Selector Inspection Functions

The SASS built-in selector module provides a set of functions for inspecting and manipulating selectors in Sass. Here are a few examples:

.element {
  @debug selector-nest(); // Outputs the current selector nest
  @debug selector-extend('.extend'); // Outputs '.element.extend'
  @debug selector-append('.append'); // Outputs '.element .append'
}

In these examples, the @debug directive is used to print the results of the selector inspection functions to the console. The selector-nest() function outputs the current selector nest, while the selector-extend() and selector-append() functions modify the current selector by extending or appending to it.

Selector Generation Functions

The SASS built-in selector module also provides a set of functions for generating selectors. Here are a few examples:

$selectors: element1 element2;

@each $selector in $selectors {
  .#{$selector} {
    background-color: blue;
  }
}

In this example, the @each directive is used to loop over a list of selectors stored in the $selectors variable. For each selector in the list, a class is generated with the corresponding name and a blue background color.

Conclusion

The SASS built-in selector module provides a set of functions for working with selectors in Sass. Whether you are inspecting selectors, modifying them, or generating new selectors, the built-in selector module is a valuable tool for any Sass developer. With its flexible and powerful features, the selector module can help streamline your stylesheet and make it easier to manage and maintain.
