==========

[![Cross-browser testing status](https://saucelabs.com/browser-matrix/gss-engine.svg)](https://saucelabs.com/u/gss-engine)

Compiles and runs Grid Style Sheet (GSS) rules. GSS is an implementation of Badros & Borning's [Constraint Cascading Style Sheets](http://www.cs.washington.edu/research/constraints/web/ccss-uwtr.pdf), enabling far better layout control through building relational rules between different elements.

GSS supports the following syntaxes for defining layout rules:

* [CCSS](https://github.com/gss/ccss-compiler#readme) - direct constraints related to position and size of DOM elements

* [VFL](https://github.com/gss/vfl-compiler#readme) - horizontal and vertical spacing constraints based on [Apple's Visual Format Language](https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/AutolayoutPG/VisualFormatLanguage.html)
