Works perfectly. Couldn't ask for anything more. Thank you!
Best extension ever! Thank you!!!
Very good extension, but why not have a shortcut to reload all css source, it's will make this perfect extension ever for front-end developer
This app is good for making themes on websites. It allows to perform css changes and to save those changes. Everytime when you reload a page it will apply those changes to the specific website. It is extremely useful for people with basic knowledge of html & css.
Müthiş bir uygulama. Zaman kazandırıyor. Yapımcılara teşekkürler :)
Poor implementation. The styles does not load on page refresh unless you open the extension editor again. Also it inherits the website styles in CodeMirror editor, and as a result you end up having white text on white background. I don't have the time to debug it more, if you ask me.
I would have never expected this: this extension has changed the way I write code. This basically turns Chrome into a live typesetting system. No more developing css in the chrome debugger. No more developing css in an IDE/editor. I feel like this turns Chrome into a word processor. If I was greedy I would ask for stylus support :-) Pretty please?
finally, an awesome live css extension that auto loads my styles
♥
Very useful to avoid wiping your ideas on refresh when debugging.
