How Can I Eliminate Gaps Between Wrapped Flex Items in a Flexbox Container?

Eliminate Gaps Between Wrapped Flex Items

When organizing elements within a container using Flexbox, gaps can emerge between items when they wrap to multiple lines. To address this issue, we need to understand the concept of align-content.

align-content: The Key to Spacing

Initially, flex containers default to align-content: stretch. This distributes items evenly along the cross-axis, which is responsible for vertical spacing in vertical flex containers. To eliminate the gaps, we need to override this default with align-content: flex-start.

Distributing Flex Lines

align-content applies to multi-line flex containers, aligning flex lines (rows or columns) along the cross-axis when there's extra space. This distinction is crucial from align-items, which specifically aligns individual flex items within a single line.

Setting align-content: flex-start

By setting align-content: flex-start on the container, we effectively push the flex lines to the top of the available space, eliminating the gaps between them. This ensures that items are stacked vertically without any unnecessary separation.

Code Example

Here's an example of how to adjust the code provided:

.container {
  display: flex;
  flex-wrap: wrap;
  height: 300px;
  flex-direction: column;
  background-color: #ccc;
  align-content: flex-start;
}

By incorporating align-content: flex-start, we can achieve a clean and compact layout without gaps between the wrapped flex items, resulting in the desired stacked arrangement.
