What are the best practices for using CSS selectors?

When using CSS selectors, it's best to keep them simple and efficient. Use class selectors over ID selectors for reusability.

Why should I prefer class selectors over ID selectors?

Class selectors can be reused on multiple elements, while ID selectors are unique to a single element, limiting flexibility.

Are there any performance considerations I should be aware of?

Yes, complex selectors can slow down rendering. Aim for simplicity and specificity to improve performance.

What about using descendant selectors?

Use descendant selectors sparingly, as they can be less efficient. Prefer direct child selectors when possible.
