I saw a post from a few years ago on how to load fonts into my server and imbed them so that other viewers can see them. There was a code given that was @font-face {
font-family: yourfont;
src: url('yourfont.ttf');
} Do I put this code into the CSS portion of my document? I don't know where to put it.

Yes, you can put this code in your stylesheet or CSS document. Then you can use font-family : yourfont; to your posts or articles.

Also, don't forget to look at Google Fonts!

They make insterting fonts easy, and theres a massive selection of all types of fonts.
