yes I was actually under the opinion that it would support all CSS properties but I understand now from your response.
To use the CTabFolder would I need to install new software into my eclipse v4? because I tried call it like following:
#FirstLabel{
tab-renderer: url('platform:/plugin/org.eclipse.e4.ui.workbench.renderers.swt/org.eclipse.e4.ui.workbench.renderers.swt.CTabRendering');
shadow-visible: true;
shadow-color: #000000;
font-family: "Times New Roman";
font-size: 16px;
color: #FFFFFF;
}
within my CSS file but I think I have got the wrong end of the stick with it comes to CTabFolder!
Sorry to be bothering you I am just very confused about it!
Or for my GUI would I only be able to specify color, font, background color?
Regards,
Ann.

Hi Ann,
You have to distinguish between:
a) CSS as a Language (e.g. selectors, pseudo-selectors,...)
b) CSS-properties
We only support the very basic attributes like font, color, background
color (including some paint types), ... and some custom ones (for
CTabFolder).
I've sent a mail to this list after we shipped 4.1 where I highlight
some problems with our current css treatment because we are not
following general rules here (e.g. it is good practice to prefix custom
attributes using -vendor (e.g. -moz, -webkit,...)) and our own SDK-CSS
is not even valid CSS because the selector some of the selectors defined
are simply invalid if you read the css spec.
Sad enough I didn't get a response on it.
My personal opinion on CSS is that we advertised it completely wrong
because people now think they can apply all CSS-Properties they can in
HTML which is far from true because naturally SWT has constraints we are
not able to overcome.
I think in reality only toolkits who completely draw the UI (like Swing,
JavaFX, Browser-Rendering-Engines) are able to fully implement
CSS-Properties but as said that's my personal opinion and others may
disagree.
