I have a problem with tag. I want to set a styleclass or some style parameters for the button, but when I set styleClass="button" and styleId=""something" (I did not manage to find what this attribute is for, and there is no difference beetween situations when it's present in the tag an when it's not) where "button" is my css style class - both elements seem to change their appearance. What is more - only the field changes it's backgroundcolor and font (eg. border works for both of them). What am I doing wrong? Is it possible anyway to separate their appearance features?
