Change font

Q: I can't see the font change after I change it in Advanced. What am I doing wrong?
A: To change font in Advanced in template designer, you have to stipulate where and which text you wish the font to change. It is not possible to change the font for every thing all at once. Select one of these: Page, blog title, blog description, tabs text, date header, post title, gadget tile, gadget text, etc.

Apply to blog.
