HTML5 Please helps you look up HTML5, CSS3, etc features, know if they are ready for use, and if so find out how you should use them – with polyfills, fallbacks or as they are. So that, you can decide if and how to put each of these features to use.
The recommendations represent the collective knowledge of developers who have been deep in the HTML5 trenches. If you think the recommendation is incorrect, you can edit the recommendation for each feature and send a pull request as well.
