I am wondering, which type and version of JavaScript/CSS engines is Gnome 3 aka Gnome Shell using?

Is there any information about current version, etc?

For JavaScript the engine GJS (based on SpiderMonkey). For theming, it is used a sort of superset of CSS2. You might be interested in reading the documentation of GtkCssProvider and the migration information.

On the other hand, there are some CSS3-like operations available, such as radial and linear gradients. You might want to take a look the article Styling GTK+ with CSS to get some ideas. The article was written by the developer who wrote GtkCssProvider.

Note that GNOME Shell uses mx to draw widgets. See more on http://live.gnome.org/GnomeShell/Development – gforcada Sep 22 '11 at 11:57
Updated. Although, it would have been better to say which one :-) – gpoo Jun 06 '13 at 19:10

The JavaScript engine is GJS. The CSS is, I believe, internal - in GTK 3, all theming is done using CSS.

Thanks for the answer. I know that CSS is used for theming. However there is no information if it is CSS2/CSS3 or CSS10. – hsz Apr 27 '11 at 08:30
