What is the difference between CSS Flexbox and CSS Grid?

CSS Flexbox is best for one-dimensional layouts (a single row or column), such as navbars and rows of cards. CSS Grid is best for two-dimensional layouts (rows and columns at once), which makes it ideal for full-page layouts.

Can I use the generated CSS code as-is?

How do I center elements with Flexbox?

To center with Flexbox, set display: flex on the container, then use justify-content: center for horizontal centering and align-items: center for vertical centering. With this tool, the "Center" preset applies it in one click.

Flexbox vs. Grid

CSS Flexbox and CSS Grid are both layout modules, but they excel at different things. Flexbox is best for one-directional arrangements such as navbars and button groups, while Grid is best for two-dimensional layouts like a full page. Use the CSS Flexbox Generator for arrangements inside a component, and the CSS Grid Generator for full-page layouts.
