Mastering CSS3 Selectors (Video 13)

This video tutorial covers structural selectors in CSS, focusing on both CSS2 and CSS3. It explains how these selectors allow for control over elements based on their position within a parent, such as first-child and last-child. The tutorial also delves into more advanced techniques using nth-child and nth-of-type, demonstrating how to apply styles to specific elements within a list or group. The video concludes with a discussion on the practical applications of these selectors in web design.
