First of all, "body.target-main" makes the change to happen on the home page only. Other pages have no ".target-main" class on the body tag.

Second, "body" is not the only tag that configures the font for the page. There are other tags and classes that set the font for page elements: .head-h2, .head-h3, ..., .mm-navbar, and others. The exact list depends on the theme, so you have to use the browser's "Inspect element" function to determine what styles you are to override to change the font.
