An index of all web-related specifications, CSS properties, JavaScript interfaces, etc.
The data is heavily based on W3C/browser-specs and W3C/webref with a lot of modifications and additions. The CSS stuff is 100% scraped by myself because the Webref data wasn't sufficient for me, and the WebIDL for the JavaScript stuff is a mixture of Webref's WebIDL database and IDL I scraped myself. Note that the hyperlink ids (hashes) for the specs of JavaScript interfaces are currently not very reliable as they have to be reverse-engineered and different specs handle them differently.
