Frequently Asked Questions
What is flexbox?
CSS Flexbox is a one-dimensional layout method for arranging items in rows or columns. It distributes space efficiently and aligns content, even when sizes are dynamic.
When should I use flexbox vs grid?
Flexbox is best for one-dimensional layouts (a row of buttons, a navigation bar, a card row). CSS Grid is better for two-dimensional layouts (rows AND columns simultaneously).
