Really poor compared to the Firefox version. 1) I can't find a way to display it as it's own toolbar. 2) Can't turn on highlight/split screen mode so that I can click on various images and see the CSS in a second pane. Pretty useless. Probably due to Chrome's limitations?
Best! Ever!
It's The first extension that I install in every computer i use that has Chrome/Firefox installed. A must for web developers. Thank you Chris Pederick.
Get it for the instant visible checkmarks re validation & syntax (including css), use it for the block highlighting.
does not work click on icons and does nothing
No hotkeys for ruler and another functions
Excelente herramienta
Made the switch to Chrome (from FF) recently, and very happy to see this extension ported! Not as feature-rich as the FF version as others have noted, but very good nonetheless.
Aprovado! É um utilitário que reúne funções das mais diversas e necessárias para desenvolvedores Web. Nota 10.
