What Selector Nesting in Sass is used for?

Selector nesting in Sass is used for several purposes:

1. Enhancing Readability: Nesting selectors in Sass allows developers to structure their stylesheets in a way that mirrors the HTML hierarchy. This makes it easier to understand the relationship between styles and the corresponding HTML elements[1][2][3].

2. Reducing Repetition: By nesting selectors, developers can avoid repeating parent selectors, which can save time and reduce the potential for errors. It also makes the code more concise and easier to maintain[1][2][3].

3. Creating Modular Code: Nesting encourages a modular approach to writing CSS, where styles are isolated within their components. This can lead to more maintainable and scalable codebases[1].

4. Targeting Specific Elements: Nested selectors make it possible to target elements more specifically within their parent contexts. This is particularly useful for styling elements based on their location in the document or their state, such as :hover or :focus[3].

5. Efficient Compilation: Sass compiles nested styles into optimized CSS output. When used correctly, this can result in cleaner and more efficient...
