Why does my flexbox layout overflow its container even though I've set flex-wrap to wrap?

Answer

Flexbox layouts can overflow their containers for several reasons, even when "flex-wrap" is set to "wrap". This often happens due to fixed-width items, insufficient container space, or margin and padding issues.

Example Concept: Flexbox allows items to wrap onto multiple lines using "flex-wrap: wrap". However, if the combined width of the items, including their margins, exceeds the container's width, overflow can still occur. Ensure that item widths are flexible (using percentages or "flex-basis") and check for any additional spacing that might contribute to overflow.

Additional Comment:

Check if any flex items have fixed widths that exceed the container's width.
Ensure margins and padding are not adding extra width beyond the container's capacity.
Consider using "flex-basis" with percentages to allow items to resize dynamically.
Inspect for any additional elements or styles affecting the container's size.
