After a forceful fight trying to do some dialog styling in CSS, I find myself completely stuck. This is what I did :
I unchecked all the stylerender options except the z-index. I set the CSS property of the dialog component and describe the (quite simple) style in my CSS. (Later I also tried it with a # style in CSS, but that did not work either). Despite of the fact I unchecked all the stylerender options, the dialog has still hardcoded width, height and position. Even so I cannot get rid of the hardcoded ui-classes in the dialog.
What I would like to accomplish seems not too difficult (for me it is, however) : I want a JQDialog to be styled at 80% width, 80% height at a top of 10% and a left of 10%. And yes, I used absolute positioning, pressed (alt-) F5 to refresh my CSS and I use the latest version of CGDevTools (and the wwwroot directory).
