Frequently Asked Questions

What is CSS Flexbox?

Flexbox (Flexible Box Layout) is a CSS layout module for arranging items in rows or columns. It provides powerful alignment and distribution capabilities. Flexbox is ideal for one-dimensional layouts, while CSS Grid is better for two-dimensional layouts.

What is the difference between justify-content and align-items?

justify-content aligns items along the main axis (horizontal in row, vertical in column). align-items aligns items along the cross axis (perpendicular to main axis). For centering, use both: justify-content: center; align-items: center;

Should I use Flexbox or CSS Grid?

Use Flexbox for one-dimensional layouts (a row or column of items). Use CSS Grid for two-dimensional layouts (rows and columns together). They can be combined: Grid for page layout, Flexbox for component layout.

What is the gap property?

gap sets the spacing between flex items. It is cleaner than using margins because it only applies between items, not at the edges. For example, gap: 16px adds 16px between each item.

How do I make flex items wrap to the next line?

Set flex-wrap: wrap. By default, flex items stay on one line and may shrink. With wrap, items move to the next line when they run out of space. This is essential for responsive layouts.
