A box model fix and a JavaScript verifier
Thor Larholm wants to make sure every box is the same size.
Or, more accurately, he wants all boxes measured the same way. The result: a potentially simple JavaScript fix that will ensure, no matter the browser or mode, a page will size boxes according to the W3C box model. He admits it still needs testing, but it seems to work quite well.
Speaking of JavaScript, you may not be able to validate a script like you can a Web page, but jslint “looks for problems in JavaScript programs”.
