Frequently Asked Questions

What is CSS Flexbox used for?
CSS Flexbox is a one-dimensional layout model for distributing space and aligning items in a container, making it ideal for navigation bars, card layouts, and centering content.
What is the difference between justify-content and align-items?
justify-content controls spacing along the main axis (horizontal by default), while align-items controls alignment along the cross axis (vertical by default).
When should I use Flexbox vs CSS Grid?
Use Flexbox for one-dimensional layouts (a single row or column) and CSS Grid for two-dimensional layouts where you need control over both rows and columns simultaneously.
What does flex-wrap do?
flex-wrap controls whether flex items are forced onto a single line or can wrap onto multiple lines when they overflow the container.
