How to customize accordion and panel look

Question

I want to increase the (height) size and change the color of a spark accordion header, similarly I want to change the color of a spark panel header. Can I do this through mxml properties and css or will I need to use a custom skin?

Answer 1

I recommend creating a custom skin. That was the way Spark was designed to be customized. Specific styles and the sort are almost an afterthought.
