Over the past several years, Mozilla's collection of developer documentation for its own web browsers has turned into a wiki-editable reference of web standards for developers working with all browsers, hosting a comprehensive, no-nonsense reference of HTML, HTML5, CSS, JavaScript, the DOM, and more. If you find yourself turning to this reference frequently, dochub provides instant access to Mozilla's documentation for any HTML, CSS, JavaScript, or DOM-related topic. If you're worried that a fancy new standard might not work in an older browser, canIuse will tell you exactly how many browsers will support that new standard. Still want to use that shiny new standard? Modernizr and yepnope will let you detect missing features, and load tiny bits of code to make old browsers support the latest HTML5 hotness.
