Implementation

To use the grid, wrap each grid row in a <div> with the usa-grid class. To use a grid without padding on the right and left, use the usa-grid-full class instead.

Each grid item is written semantically by its width. For example: usa-width-one-half = ½ grid item, usa-width-two-thirds = 2/3 grid item.

Medium breakpoints are used for 1/6 and 1/12 grid items, which both transform into a 1/3 grid item at medium screen sizes.

All grid items are full-width at small screen sizes.

Accessibility

  • Low-vision users should be able to increase the size of the text by up to 200 percent without breaking the layout.

Usability

When to use
  • Almost always use a grid layout — visitors can read more quickly on pages that use grids. Choose a single grid system for your entire site.
When to consider something else
  • Avoid mixing this grid and other grid systems.
Guidance
  • Choose a 12-column grid with flexible column widths and fixed gutters. The width of the padding on the left and right edge of the grid depends on device size.
  • Avoid text lines longer than 75 characters. Place text in narrower grid boxes to keep text lines from becoming too wide.
