DevDays® is for web designers and cloud developers. The site provides news and tutorials on cloud and web technology.
See our 32 part getting started series on HTML5, CSS3.
Still to come, Single Page App development and Cloud architecture.
Sample code can be found on the DevDays GitHub repository. The goal of the samples is to show how you can implement the feature, but also to provide context. When I was learning I often found that the snippets were great, but I wanted to understand how all the parts fit together. Hopefully the samples provide that for you.
