Apply Flexbox best practices

Flexbox is one of the most used CSS features, but its unintuitive default values (flex-shrink:1, min-width:auto) cause layout bugs that are hard to diagnose. Understanding the flex shorthand and the min-width:0 fix prevents the most common Flexbox breakage scenarios.

Quick Reference

• Flexbox is for one-dimensional layouts (a row OR a column)
• Use flex: 1 1 0 (shorthand: flex:1) for equal-width items that fill space
• Add min-width: 0 to flex children when text overflow truncation doesn't work
• Use gap instead of margin for spacing between flex items

Check

Review this CSS for common Flexbox mistakes: missing min-width:0 on text-containing flex children, using margin instead of gap for spacing, and improper flex shorthand usage.

Fix

Fix the Flexbox layout issues: add min-width:0 where needed, replace inter-item margins with gap, and correct flex shorthand values.

Explain

Explain how flex-grow, flex-shrink, and flex-basis work, what the flex shorthand means, and why min-width:0 fixes text overflow in flex layouts.
