What is CSS?

CSS stands for Cascading Style Sheets, and it is used to control how a website looks. CSS includes colours, fonts, spacing, and layout. 

Why is CSS important in web design?

CSS ensures websites are visually consistent, responsive, and easier to maintain, instead of having layouts and styles manually tweaked page by page. This makes the process a whole lot faster. 

Does CSS affect website performance?

Well-written CSS can improve loading times and user experience, while messy CSS can slow things down and cause layout issues.
