Semantic HTML

Semantic HTML

Use semantic elements like header, nav, main, section, and footer. HTML and CSS together form the visual foundation of every website. While HTML provides the structural skeleton, CSS brings the design to life with colors, layouts, typography, animations, and responsive behavior. Mastering semantic html is essential for creating professional, user-friendly web experiences that work across all devices and browsers. These skills are the building blocks that every frontend technology — React, Vue, Angular — is built upon.
