I'm looking for a free/gratis (online or offline) CSS 3 Editor.

I found this one http://www.cssportal.com/online-css-editor but it is way too basic.

Plataforms: online / windows.

    What features do you want? If that is "too basic", what is missing. Which o/s for offline use? The more information that you give us, the more that we can help you.

    Visual Studio isn't bad either and there is also a free version (community edition 2013)

  • Thanks for your update, Azevedo – but that's still not sufficient to re-open the question. See the first comment (of Mawg) for what's missing.

Backets is an open source HTML, JS and CSS editor sponsored by Adobe. It's clean and comfortable to use if you already know CSS. It includes a "live preview" option and can extract design information from PSD files. There are also extensions for you to add extra features.


You have given so little information that it is difficult to advise you.

However, you can hardly go wrong with Amaya, since it's a project from the The World Wide Web Consortium (W3C) and so shines in the area of standards compliance and accessibility.

Work on Amaya started at W3C in 1996 to showcase Web technologies in a fully-featured Web client. The main motivation for developing Amaya was to provide a framework that can integrate as many W3C technologies as possible. It is used to demonstrate these technologies in action while taking advantage of their combination in a single, consistent environment.

Amaya started as an HTML + CSS style sheets editor.

    Except that the last version was released on 18 January 2012, and a lot has changed since then.

I would suggest you:

  • Liveweave (http://liveweave.com) is a HTML5, CSS3 & JavaScript editor with real-time (live) preview

    Why? Have you used it? What features make it stand out? Or did you just Google & paste the first hit?

    I have used it in the past and I was very comfortable with the features it offers. CSS3 which is one of your request more than this I was using other tools may be less relevant to you as color palette, text generators and so on...

  • It wasn't my question. Since you are new around here, I was pointing out that we like more detail in our answers. Even that comment helped a little, so I up-voted it. Welcome aboard!

    What @Mawg was pointing to is what makes a quality question (I recommend to check that link ;) Also, important details (as your previous comment) should be integrated with your answer itself (you can always edit it to improve) – in the comments it might get lost. At this place usually comes the hint to point out how your recommendation meets the OP's requirements – but considering the OP didn't specify any, that would be in vain. Still, one thing was specified: is it free? Does it work online – or offline?
