Hi,
If you want to add your own font and to be all ok, you will need to know a little css to put everywhere you want that font, but the way that I figured out and it is working more than perfect it is:
1. Go into your ftp: design/templates/your_theme/templates/ and open index.tpl and put after this line
"<link href="{$logos.favicon.image.image_path}" rel="shortcut icon" />" your link with font if it is from google fonts.
or
1a. If you have font as .woff (like for mogabume) than go to: design/templates/your_theme/templates/common/ and open styles.tpl and after {style src="scheme.less"} include your font, but be patience you will save .wofff files on
css folder.
After that go into css when you want to put your font and write or change with your font.
For example if we have economica from google web fonts we put:
<link href='http://fonts.googlea...talic,700italic' rel='stylesheet' type='text/css'>and we call font in cs file as:
font-family: "Economica";I hope this will help you
