Frequently Asked Questions

What is CSS Flexbox?
Flexbox is a one-dimensional layout method in CSS that distributes space and aligns content in a container. It is ideal for navigation bars, card layouts, and flexible content areas.
Can I see the live preview?
Yes. As you adjust direction, alignment, justify, wrap, and gap settings, the preview box updates instantly with colored child items showing the flex behavior.
Can I add multiple child items?
Yes. You can add up to 8 child items, each with its own flex-grow, flex-shrink, and flex-basis settings. Remove items as needed.
