I am using uniGUI Professional Edition v1.0.0.1397.
I added a TUniButton component in my form. I need to create a CSS class to add on this button.
In the browser, under "Inspect Element" I can see that this button has an "x-btn-default-large" class.
I want to add another class to this button. But I do not know where and how to create this class, or how I add the class to that button.
