CSS selectors are a core concept in web development, enabling developers to target specific HTML elements for styling.

They are considered the 'bread and butter' for applying CSS rules, requiring careful thought on which elements to target and how to write clean, effective rules.

Two key best practices for using CSS selectors are:
4
Specificity**: Avoid making rules more specific than necessary, but also don't make them overly generic (e.g., targeting every `div`).
5
DRY (Don't Repeat Yourself)**: Strive to write CSS rules that are not redundant, promoting maintainability and efficiency.
