Use CSS Grid when items need to align across rows and columns; use Flexbox when they need to flow or distribute along one axis at a time. They solve different layout problems and can be combined in the same interface.
What is the difference between CSS Grid and Flexbox?
Flexbox lays out items along one main direction: a row or a column. Grid coordinates two dimensions, controlling rows and columns together. The distinction is about how items relate to one another—not whether a layout is a large page region or a small component. MDN Web Docs explains the two models in its guides to Grid’s relationship to other layout methods and Flexbox’s relationship to other layout methods.
| Question | Flexbox | Grid |
|---|---|---|
| How many dimensions are coordinated? | One axis at a time: row or column. | Rows and columns together. |
| What drives sizing? | Content and available space influence how items size and share space. | Tracks and placement establish a structure; tracks can also respond to content. |
| What happens when items wrap? | Each line distributes items independently. | Items can share defined row and column tracks. |
| What is a useful starting point? | A toolbar, navigation row, or content-led group arranged in one direction. | A card listing or page structure whose rows and columns need coordinated alignment. |
These are practical cues rather than rigid rules: either method can appear in a component or a page layout.

Start with Flexbox when the relationship that matters is a single row or column. It is suited to items that should flow in one direction, with flexible sizing, alignment, or distribution of remaining space. A navigation row or toolbar, for example, may need its items aligned and spaced without establishing shared columns with other rows.

Flexbox is content-out: item content and available space help determine sizing. That makes it a natural choice when the items themselves should influence how the available room is divided. Its container can set the direction, allow wrapping, and control alignment. See MDN’s basic concepts of Flexbox.
When should you use CSS Grid?
Choose Grid when the design depends on coordinated rows and columns—for example, a card listing where cards on different rows should line up to common column edges. Grid lets you define fixed or flexible tracks, including tracks sized with fr, and place items using lines, named lines, or named areas. Items can also be auto-placed when you do not specify every position. MDN’s CSS Grid guide covers these layout capabilities.
Grid is layout-in: you define a track structure and place content within it, although tracks can still respond to content. It can also support overlapping items when the intended design calls for layers.

No. A wrapped Flexbox container creates multiple lines, but each line distributes its items independently. The items in one line do not automatically align to shared columns with items in another line.

If cards on separate lines must share column edges or consistent track sizing, use Grid. Giving Flex items fixed widths to imitate shared columns can make the layout brittle; MDN discusses this distinction in its guide to Flexbox and other layout methods.
Can you use Grid and Flexbox together?
Yes. Choose the method for the relationship inside each container. A page can use Grid to coordinate its main regions and Flexbox for a one-directional arrangement within one region. The reverse can also make sense if the page flows in one direction but a nested component needs shared rows and columns. Alignment concepts transfer between the two because both use CSS box-alignment features.
How should you decide for a real layout?
- Identify the relationship. If only a row or column matters, begin with Flexbox. If rows and columns need to coordinate, begin with Grid.
- Decide what should drive sizing. Use Flexbox when content should influence how available space is divided; use Grid when a planned track structure should guide placement.
- Check alignment across wrapped lines. If items on different lines must share column edges or sizing, choose Grid rather than relying on wrapped Flexbox.
- Evaluate nested containers separately. Combine the methods when different parts of the interface have different layout relationships.
MDN’s CSS layout cookbook presents layout as a choice among patterns and methods; for columns, it identifies Grid, multicolumn layout, and Flexbox as alternatives to consider.

Grid and Flexbox are responsive layout methods, but neither guarantees that content will remain readable at every available width. Check how text line lengths and item sizes behave as the viewport changes, and add breakpoints when the design needs a different arrangement. MDN’s responsive design guide discusses layout methods alongside line-length control and breakpoints.
