The best bookmarklets on the web
9th April 2003
Via Eric Meyer, the best bookmarklets collection on the web. Make a bee line for the Web Development Bookmarklets and grab test styles and shell (both Netscape / Mozilla only)—shell brings up a javascript console shell which can actively modify the DOM of the current page, while test styles (easily the most useful bookmarklet I’ve ever used) allows you to make live, dynamic changes to the CSS currently affecting the document. You type CSS statements and as soon as they are complete enough to be parsed they are applied to the current page. The other bookmarklets are well worth a look as well, especially ancestors which displays the CSS selector hierarchy of the element under your mouse pointer in the browser’s status bar.
