Methodology is important: Progressive Enhancement vs Graceful Degradation

This week you will make another step in mastering RWD. And this is a methodological step. You can understand the components of RWD well but might start having methodological problems, that sometimes can kill a project.
    

Please read http://www.peachpit.com/articles/article.aspx?p=1586457 to get a better picture of this approach. Compare with top-down Graceful Degradation...

It doesn't mean that graceful degradation (especially if done right) is wrong :) This depends on the type of your project, its use cases, and your resources. There are proponents stating that in some cases they want to show the best modern technology can offer in order to beat the competition and demonstrate the latest advantages. Then there are only three ways: progressive enhancement, creating a separate advanced site, or use graceful degradation techniques that analyze the context and start simplifying/dropping some features depending on the situation. This requires knowledge of additional "context sniffing" and project simplification methods, more coding, but can still lead to an RWD version that will work on all devices and browsers with automatic adjustments.
