Common questions
What does the 'fr' unit mean in CSS Grid?
The 'fr' unit represents a fraction of the available free space in the grid container. '1fr 2fr' means the second column gets twice the space of the first. It's similar to flex-grow but specifically designed for grid track sizing.
Is CSS Grid supported in all browsers?
Yes. CSS Grid has excellent support in all modern browsers (Chrome 57+, Firefox 52+, Safari 10.1+, Edge 16+). It covers over 97% of global browser usage, making it safe for production use.
