Align-Items vs. Align-Content in Grid Layout: A Detailed Distinction

In Grid Layout, align-items and align-content properties are crucial for achieving desired item and grid alignment within the container. However, their distinct roles can be confusing.

Terminology clarification:

• Grid Container: The surrounding element that defines the grid area.
• Grid: The matrix of vertical and horizontal lines dividing the container into areas.
• Grid Items: Content blocks contained within the grid areas.

Align-Items vs. Align-Content:

-Items: Controls the alignment of grid items within their individual grid areas.
-Content: Controls the alignment of the grid as a whole within the container.

Understanding the Difference:

The misconception arises from the idea that justify-content and align-content apply only when the grid size is smaller than the container size. However, this applies to both -items and -content properties.

If the grid fits perfectly within the container, there will be no space for the container to distribute for alignment. In such cases, both -items and -content alignment will have no effect.

Graphical Example:

Consider a grid container divided into three equal-sized areas vertically. The grid items are placed in the second and third areas. The grid and container are of unequal sizes.

Align-Items:

• align-items: center; Aligns the items vertically within their respective areas.
• justify-items: center; Aligns the items horizontally within their areas.

Align-Content:

• justify-content: center; Spaces the grid horizontally within the container.
• align-content: center; Aligns the grid vertically within the container.

Conclusion:

-Items properties align items within grid areas according to the grid container's specified dimensions.
-Content properties align the grid as a whole within the container, taking into account any available space or overhang.
