Difference Between align-content in Grid and Flexbox
The align-content property in both Grid and Flexbox is used to align the entire content along the block (vertical) axis when there is extra space. However, its behavior differs slightly due to the way Grid and Flexbox handle layout.
In Grid, align-content aligns the entire grid within the container when the total grid height is less than the container height.
In Flexbox, align-content aligns the flex lines within the container when there are multiple lines (i.e., flex-wrap: wrap is used).
If there is only one line of items in Flexbox, align-content has no effect; Grid always treats the grid as multiple tracks for alignment purposes.
Both support values like start, end, center, stretch, space-between, space-around, and space-evenly.
