Previous Question Next Question

CSS Grid's "auto-fill" and "auto-fit" properties are used in the context of the "repeat()" function to handle grid items dynamically. They determine how grid items are placed and how empty tracks are managed.

Example Concept: "Auto-fill" fills the grid container with as many columns or rows as possible, even if some are empty, while "auto-fit" collapses any empty tracks, adjusting the grid to fit only the available items. This distinction affects how the grid adapts to different screen sizes and content amounts.

Additional Comment:

"Auto-fill" is useful when you want to maintain a consistent grid structure, even if not all slots are filled with content.
"Auto-fit" is ideal for responsive designs where the grid should adjust to the number of items, eliminating empty spaces.
Both properties are often used with "minmax()" to define flexible grid item sizes.
Experimenting with both can help determine which best suits your layout needs.
