Abstract:

A style guide is essential for a successful project. Many of our clients have their own style guidelines, which we follow to ensure that our work matches what they produce in-house. However, some clients do not have internal style guides. We have developed our own style guide to ensure our work on their projects is consistent. Putting the style guide on the web eliminates distribution problems and ensures that we always use the latest version.
