What's the Difference Between `justify-content`, `justify-items`, and `justify-self` in CSS Grid?

Understanding the Differences Between justify-self, justify-items, and justify-content in CSS Grid

CSS Grid layout offers a range of properties for aligning and distributing grid elements. However, navigating the similarities and differences between justify-self, justify-items, and justify-content can be confusing. This article aims to clarify their distinctions.

1. Flexbox vs. Grid Properties

Unlike justify-self and justify-items, justify-items is not a property in Flexbox. This is due to Flexbox's one-dimensional nature, where aligning multiple items along the axis poses challenges. In Flexbox, justify-content serves as the primary means of item alignment.

2. Purpose of justify-content, justify-self, and justify-items

• justify-content: Aligns grid items along the row axis (horizontal), ensuring they are evenly distributed within the grid container.
• justify-items: Positions the content within each grid item along the row axis, adjusting the horizontal alignment of its child elements.
• justify-self: Controls the alignment of a specific grid item within the grid row, providing more granular control over individual item placement.

3. Differences Between justify-content, justify-self, and justify-items

The key differences lie in their scope and level of control:

• Scope: justify-content affects the alignment of all grid items in a row, while justify-self and justify-items work at the level of individual grid items and their contents.
• Granularity: justify-content provides alignment options for the entire row, while justify-self allows for the alignment of individual items within the row, and justify-items handles the alignment of content within those items.
