Question

I know that I need to modify the template. But what exactly? I am using Fogbugz 8 template.

Answer 1

You'll be looking to customize the .article-content section of the template's CSS:

By default, the FogBugz 8 wiki template has the font set as follows:

.article-content {
    font-family: Cambria,Georgia,'Times New Roman',Times,serif;
}
