I have a major problem with styling GXT3 in general which I try to explain with an example:

Let's say I have a BorderLayoutContainer and I want to change the background color. What I did is´:

Code:
BorderLayoutContainer con = new BorderLayoutContainer();
con.addStyleName("custom-blc-style");
In may CSS file (which I included in the EntryPoint HTML page after the reset.css) I added

Code:
.custom-blc-style { background: green; }
According to Fierfox' "Insepct Element" the DIV's style is "div.GB2UA-DDGSB.custom-blc-style".

Checking the styles I see that my style ".custom-blc-style" has been overridden by some inline style named ".GB2UA-DDGSB".

What did I wrong?

Thanks,
Hannes
