Fixing Broken Layouts in CSS Grid & Flexbox

Modern CSS tools are powerful, but misusing them can lead to frustrating layouts.

Common Problems

1. `overflow: hidden` causing content clipping.

2. Nested flex items not respecting parent sizes.

3. Grid rows collapsing due to no height.

Use `outline: 1px solid red;` to inspect element boundaries.

Use DevTools' Flex/Grid overlays.

Watch for min/max-width conflicts.

.flex-container {
  display: flex;
  flex-wrap: wrap;
  gap: 1rem;
}

Knowing how layout engines behave helps you avoid wasting hours debugging UI bugs.
