Released yesterday, dabblet joins an array of live sandbox tools designed to prototype, test and share webcode that includes JSFiddle and CSSDesk, while bringing some advantages of its own.
Other useful resources: w3clove validates an entire site, rather than page-by-page; JQuery Air teaches you how to use the framework directly in the browser; domain.nr finds clever TLDs for your site, and Sequel Pro is a nice, free, native, open source MySQL editor for OS X. If you’re more the old-school dead-tree type, there’s always The Manual.

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.

What the Heck is Shadow DOM? Browser developers realized that coding the appearance and behavior of HTML elements completely by hand is a) hard and b) silly. So they sort of cheated. They created a boundary between what you, the Web developer can reach and what’s considered implementation details, thus inaccessible to you. The browser however, can traipse across this boundary at will.

Customization of a page was never easier. Mark Newhouse of iBook, iMac, iBlog, has come up with this really cool way of skinning the blog using CSS via a nifty adaptation of a script by Porter Glendinng. Now if we could mix this concept with Jason's modification via cookies, you'd get a skinnable site rather than a skinnable page using just CSS and Javascript. [Found the site via Zeldman]

Jason found a pretty cool javascript/CSS hack so I took a stab creating a bizarro kottke one (bookmark and try it at kottke.org). I think it improves the page :). This might be a killer hack for usability tweaking. If you set your backgrounds dark with light, 28px text for easy reading, few web pages follow that convention. Here's your chance to see things your way. Can anyone think of any other uses for this?
