It seems this great theme is getting more and more popular. The threads are increasing rapidly.

I wanted to change the font-family and font-size of the post title. I modified CSS files at the Montezuma Options in the admin panel, but no success.
I changed the font-size of ".hentry > h2" part and ".hentry > h1" part in posts.css,
the font-family and font-size in h1 ~ h6 headings part in content.css.
Unfortunately, Nothing changed. Is there anything I missed?
Thanks.
