The Fluid Baseline Grid System is an HTML5 & CSS3 development kit that provides a solid foundation to quickly design websites with ease. I found this responsive grid system and thought it was a great building block for a Drupal theme. The Fluid Baseline Grid System is released under anUnlicense license and therefore is considered in the public domain. Feel free to modify the layout based on the usage example below.

The FBG system was built with typographic standards in mind and combines principals of fluid-column layouts, baseline grids and mobile-first responsive design into a resolution independent and device agnostic framework. It is packed with CSS normalization, beautiful typographic standards, corrected bugs, common browser inconsistencies and improved usability. You can finally have your cake and eat it too, all while making awesome websites.

Fluid Columns

The FBG system facilitates creativity by providing a framework for composition. Grid systems create visual rhythm and structural balance to enhance the experience with predictable patterns.

FBG is defaulted to a minimal 3-column folding grid, which is easy to work with and divided into equal portions, 31.333% wide with 2% wide gutters between columns. This is a starting point, not a standard, so we encourage you to change the columns as your project requires.

Baseline Grid

The typography of FBG is designed to establish a typographic hierarchy that improves readability and creates harmony within the text. Measure, leading, vertical rhythm, emphasis and scale are something we obsess about.

The primary font is Georgia, but the font stack can be easily changed. Paragraphs are set at a 16px base with 150% (24px) line height to improve readability and improve the appearance of text. We encourage you to change the base font size and line height to suit your needs.

Responsive Design

The FBG is designed for mobile first. CSS styles are scaled up from the minimum instead of scaled down from the maximum through the use of media queries. IE6/7/8 do not support media queries, so Respond.js is used to polyfill.

Common Break Points

* 320 px — Mobile portrait
* 480 px — Mobile landscape
* 600 px — Small tablet
* 768 px — Tablet portrait
* 1024 px — Tablet landscape/Netbook
* 1280 px & greater — Desktop

Normalize CSS

Reset vs. Normalize? Most web designers use either the Eric Meyer Reset or the YUI Reset, but a reset doesn't fix cross-browser inconsistencies or preserve useful defaults. Normalizing CSS allows for the preservation of useful defaults, while correcting bugs, fixing common browser inconsistencies and improving usability. Many thanks to Nicolas Gallagher and Jonathan Neal for researching the differences between default browser styles in order to precisely target only the styles that need normalizing.


The code for FBG is simple, lightweight, and non-obtrusive, which allows it to be easily modified for each project. The default is based on a 3-column folding layout. 1 column for mobile devices, 2 columns for tablets and 3 columns for desktops and beyond. The only necessary provision is to add either class="g1", class="g2" or class="g3" to each you would like to make a column.
G1 = 1 column wide
G2 = 2 columns wide
G3 = 3 columns wide


  <div class="g2">
  <div class="g3">
  <div class="g1">

Browser & Device Support

The FBG System is designed to be cross-browser compatible and device independent: Firefox 3.5+, Opera 11+, Chrome 11+, Safari 5+ and Internet Explorer 6+.
