I have the jsf code and css code below. I'm having trouble getting the css margin attributes to take effect. All the other attributes work fine except margin. What am I doing wrong?
Notice the .contentDialog css class is applied to p:dialog. What I expect is a 100px margin around h:outputText enclosed in f:facet name="header". But it's not happening.
I've tested on IE 7, IE 8, FireFox 7.0.1 and Chrome 16.0.912.63 m. Same problem on all browsers. Also, I'm using PrimeFaces.
