Typography
Bootstrap typography utilities provide consistent heading scales, display styles, text alignment, weight, line-height, wrapping, and other readable text treatments.
Core concept
Explain the difference between semantic HTML headings and visual display classes. A large visual heading should not require breaking the document\'s heading hierarchy. Cover lead text, text-muted alternatives, font weight, text alignment, text transformation, and responsive text utilities.
Using it in a real interface
Show how typography works inside cards, hero sections, forms, and navigation. Explain that readable line length, contrast, and spacing are design concerns in addition to font size.
Implementation notes
Prefer semantic elements such as h1, h2, p, ul, and blockquote, then use Bootstrap classes to change appearance. This keeps content meaningful when CSS is removed or modified.
