How to Eliminate Gaps Between Wrapped Flex Items in a Column?

Remove Space (Gaps) Between Multiple Lines of Flex Items When They Wrap

When using flexbox with a set container height and a direction of column, it's possible to encounter gaps between lines of items when they wrap. This issue arises due to the default align-content property set to stretch, which distributes lines evenly within the available space.

To remove these gaps, adjust the align-content property:

css
.container {
align-content: flex-start;
}

This sets the alignment for flex lines (rows) to the start of the container, effectively eliminating any gaps between lines.

Understanding Flex Line Alignment

It's important to note the distinction between align-items and align-content:

• align-items: Aligns items within a single flex line (row or column) on the cross axis.
• align-content: Aligns multiple flex lines within the container on the cross axis.

In the case of a multi-line flex container, align-content is responsible for distributing the space between rows or columns. By setting align-content to flex-start, flex lines are positioned at the start of the container without any gaps.

Additional Tips

Consider adding other flexbox properties to fine-tune the layout:

• justify-content: Align items within each flex line on the main axis.
• align-items: Set vertical alignment within each flex line.
• flex-direction: Specify the layout direction (row or column).
• flex-wrap: Determine whether items wrap to multiple lines.
