Hi, i'm kinda new to this wiki thing. I'm trying to create my own custom infobox for conmyth.wikia.com; I'm almost done with it; done the template article and thanks to the infobox builder, i did the chart pretty fast. The problem is that I'm not completely satisfied with the wiki's predetermined color, and i'd like to choose my own color for the infoboxes, maybe even choosing a different title background depending on the character. The problem is that with these portable features i'm not sure how to change the color. http://conmyth.wikia.com/wiki/Template:FoCharacter?action=edit&useeditor=source. That's the template page I created, as you can see the only thing left is the color thing. I've read many questions like this but didn't understand the answers. Am I supposed to change the MediaWiki:CSS page? or I can do it by just css in my own template? Sorry for the repeated question :/
