Frequently Asked Questions
What is the difference between auto-fit and auto-fill in CSS Grid?
auto-fit collapses empty column tracks and stretches existing items to fill the row width, while auto-fill reserves empty space for unoccupied tracks.
How does repeat(auto-fit, minmax(200px, 1fr)) replace media queries?
The browser automatically computes how many 200px columns fit inside the container, wrapping cards onto new rows dynamically without needing breakpoint media queries.
