This is the default template designed for web applications in WorkSafe BC. It has a fixed width and works on any device and platform. The fluid template can be used by designers and developers to quickly get out of the ground and start building applications.
Developers love templates and wrappers they can use right out of the box, they don't want to to go and ask designers about how many pixels of margin and paddings are here or there. They just want to look at the code and vualá! start working. No need to pull Photoshop files and gimmicky design tools to extract CSS.
Designers don't have to do the math or ask developers to build templates from them. Designers can use the pre-canned fixed template and start placing elements inside the grid, just like playing a tetris game.
