Bootstrap 5.3 Layout System
Bootstrap's layout system is built on flexbox and provides a powerful 12-column grid for creating responsive layouts. This skill covers containers, the grid system, breakpoints, and layout utilities.
Breakpoints
Bootstrap's responsive design uses six default breakpoints:
| Breakpoint | Class infix | Dimensions |
|---|---|---|
| Extra small | None | <576px |
| Small | sm |
≥576px |
| Medium | md |
≥768px |
| Large | lg |
≥992px |
| Extra large | xl |
≥1200px |
| Extra extra large | xxl |
≥1400px |
Breakpoints apply at the specified width and up (mobile-first).
