Using Custom Font

I'm tying to use a cursive font on the Generatepress site the same way we currently use it on the existing site, right below the hero image. (The text-shadow is just how we're using it, but that part is working fine and unrelated to the problem).

I'm a bit miffed at what could be the problem, since importing the font-face works the same way as on the existing site. Is there something that perhaps GeneratePress is doing to not allow it to happen?

@font-face {font-family: XXX; src:url([URL]XXX.woff);}
.cursive {
font-family: XXX;
text-shadow: 1px 1px 2px #636363;
}
