HTML and CSS foundations

Build structured, styled, responsive pages.

📖 Key ideas

  1. Semantic HTML: header, nav, main, section, footer.
  2. Forms collect input: input, select, textarea, button.
  3. CSS selectors, box model, Flexbox and Grid.
  4. Responsive design with media queries and mobile-first CSS.
  5. Accessibility: alt text, labels, contrast.
💡 Real-life example: HTML is the skeleton, CSS is the clothes, and responsive design means the clothes fit any body size.
