FAQ

What's the difference between Grid and Flexbox?

Flexbox is designed for one-dimensional layouts (a single row or column), while Grid handles two-dimensional layouts (rows and columns together). Use Flexbox for simple alignment tasks and Grid for more complex page or component layouts.

Does the generated CSS work in all browsers?

Yes. Both CSS Grid and Flexbox are supported in all modern browsers, so the generated code works without additional vendor prefixes or fallbacks.

Can I use this for a full page layout?

Yes, though for full-page layouts you'll typically want to combine this generated container CSS with your own responsive breakpoints and content-specific styling.
