New features include a fully fluid grid layout
The Square Grid affords column-based and golden-ratio-based designs

Lightweight. Responsive. Mobile-first. Content-first. HTML5. Square Grid theme provides a framework for your page layout ... and that's it. It incorporates responsive design settings to present usable layouts for mobile and desktop. That's it. We want your theme to load quickly, with as little grid framework css as possible.

The Square Grid has some nice advantages over other grids:

  • Flexibility: Its 35-column breakdown of space allows great flexibility in grid selection, including popular favorites 6-, 9- and 12-column grids, as well as Golden Ratio layouts.
  • Resizability: Its algorithm is easily adapted to various screen sizes.
  • Whitespace: Gutters are defined by the squares, resulting in pleasing whitespace between columns while staying within the grid framework.
  • Use of screen estate: It uses the full width of the grid; no dead space on the left and right sides within the grid.



  • HTML5
  • ARIA roles
  • Fully responsive design
  • Mobile first
  • Content first
  • Fluid layout of grid display
  • Configurable width settings for sidebars and design break-point
  • Configurable layout of content and sidebars (e.g., both sidebars on left, both on right, etc.)
  • Configurable inclusion of html5shiv for older Internet Explorer browsers
  • Configurable "web app" mode for iOS browsers

This branch ends up with a lighter footprint than 7.x-2.x, with fewer lines of css as well as improved markup cleanup for easier theming.

Installation and Use

Install the theme as normal. It's recommended to use Square Grid as a base theme for your own theme. Configuration settings can be found in your sub-theme's Theme Settings.
