FAQ

HTML

What typical mistakes occur when writing HTML?
Typical mistakes are skipped heading levels, clickable elements built from div instead of button or a, missing labels on form fields, and images without alt text. Nested wrapper elements with no purpose also bloat the code. A validator and a keyboard test catch many of these errors quickly.
How does HTML differ from CSS and JavaScript?
HTML provides structure and content, CSS provides presentation, and JavaScript provides behavior. A page should remain readable and basically usable without the other two layers, which is the idea behind progressive enhancement. Generating structure only through scripts makes content fragile and harder to access.
Why do the right elements matter in HTML?
Elements carry meaning: a button is operable by keyboard, a heading shows up in screen reader navigation, and a nav element marks navigation. A div with a click script offers none of that without extra work. Semantic HTML therefore improves accessibility, maintainability, and processing by search engines without being visible on screen.
