Bootstrap 5 On Point

Official source

Actual coverage

HTML; CSS; Bootstrap introduction; CSS components; JavaScript components; layouts; utility classes; icons; an admin-dashboard project; and customization.

Durable knowledge

  • Semantic HTML gives content structure; CSS controls presentation; Bootstrap supplies a consistent design vocabulary on top.
  • Responsive layout starts mobile-first and adds behavior as space increases.
  • Grid systems coordinate containers, rows, columns, gutters, and breakpoints.
  • Components accelerate delivery but must retain meaningful HTML, keyboard behavior, accessible labels, and visible focus.
  • Utility classes are efficient for local styling; repeated complex combinations should become a component or custom style.
  • Customize design tokens rather than fighting framework defaults with scattered overrides.

Proof checklist

Check narrow and wide screens, content overflow, keyboard navigation, contrast, focus, form errors, modal/dropdown behavior, and reduced-motion preferences.
