Responsive Grids

A layout should be fluid, not just "breakpoint-dependent." This skill explores the power of modern CSS for flexible design.

CSS Grid

• Auto-Fill vs. Auto-Fit: Create many-column layouts that adjust automatically without media queries.
• Fractional Units (fr): Flexible distribution of space.
• Grid Areas: For semantic, easy-to-read layout structures.

Flexbox

• Alignment: Mastering justify-content and align-items.
• Flex-Grow/Shrink: Controlling how items fill or squeeze into space.
• Gap: Using the modern gap property instead of margin hacking.

The "Modern" Breakpoint

Instead of hardcoding device widths, use minmax() and clamp() to create truly fluid typography and layouts. width: clamp(300px, 50%, 800px);
