Corvus's responsive grid system is designed for desktop, tablet and smartphone systems, each with minor modifications to ensure compatibility in each mode. The table above shows the breakdown of screen resolutions and associated devices, and what layout characters are then applied to each.
Another useful feature available, via Bootstrap, is the collection of responsive utility classes that can be used to help tweak layouts by providing a simple method of showing or hiding modules. Insert the above module class suffixes into your settings to show/hide a module for a particular mode.
Corvus, August 2013 template release, is designed with a versatile visual model, an intricate mix of subtle style elements to add depth to elements whilst maintaining an overall conservative edge.
