Frequently Asked Questions
What is CSS Flexbox?
Flexbox is a one-dimensional layout system for arranging items in rows or columns. It's perfect for components and small-scale layouts.
What's the difference between justify-content and align-items?
justify-content controls spacing along the main axis (horizontal for row). align-items controls alignment along the cross axis (vertical for row).
When should I use flex-wrap?
Use flex-wrap when you want items to wrap to new lines if they don't fit in one line. wrap creates multi-line flex containers.
What does flex-grow do?
flex-grow determines how much an item should grow relative to others when extra space is available. Higher values = more growth.
Can I use flexbox for entire page layouts?
Yes, but CSS Grid is often better for full page layouts. Flexbox excels at component-level layouts like navigation bars, card rows, etc.
