What's the Difference Between `align-items` and `align-content` in Flexbox?

Distinguishing align-content and align-items

Within the realm of flexbox, both align-content and align-items bear significance in organizing the layout of elements. However, their respective roles differ:

align-items

Similar to justify-content, align-items governs the alignment of items within a flex container along the cross axis. By default, align-items falls along the vertical axis in a horizontally-oriented container (flex-direction: row) and vice versa for vertically-oriented containers.

align-content

Unlike align-items, align-content takes effect when there are multiple lines of elements within a flex container. It influences the alignment of the entire arrangement of elements, rather than individual items.

Here's a demonstration of their distinction:

align-items: center

This ensures that items within a single line align vertically at their center, regardless of varying heights.

align-content: space-around

This evenly spaces out lines vertically, allowing for more harmonious spacing when dealing with multiple lines of elements.

It's also worth noting that combining align-content: space-around with align-items: center aligns the last line vertically centered.
