I have changed the font size of post and page headlines in Atahualpa 3.7.1 to something smaller than the default value, as I found them to be too big. However, now in the body of "page" pages the h1, h2 and h3 font sizes are all disproportional when compared to the page title font size (h1, h2 and h3 now look too big).
How can I change those values? I realize that this might NOT be an Atahualpa question, but I'm quite new to CSS and have absolutely no clue how to change this. Any help or link to an external info source will be greatly appreciated!
