Typography Is Interface Design
Typography is one of the most important parts of web design because users spend large amounts of time reading headings, labels, forms, instructions, cards, and long-form content. Strong typography improves comprehension and confidence.
Basic Font Styling

Responsive Typography Thinking
Typography should work well on phones, tablets, and desktops. Students should understand that text sizing and line length must support reading comfort, not just visual style.
Hierarchy and Contrast
Headings, subtitles, body copy, labels, captions, and helper text should be clearly distinguishable. This hierarchy often matters more than fancy effects.
Real Example
A documentation page with cramped line height and weak heading contrast becomes tiring to read. Better typography can dramatically improve user understanding without changing any underlying content.
