Fairly new to this but I do understand the basic concepts on needing to change code etc. Was wondering if anybody knows or could tell me whereabouts the code in the stylesheet.css for post header and the actual post's font size is. I know it probably sounds very basic but have been reading help off google and have been playing around with it but can't find it for the life of me!
