If you want to use a TTF font (standard font file) on your website you need to start by defining your font in CSS:
@font-face {
font-family: typewriterFont;
src: url(../fonts/typewriter.ttf);
}
body {
font-family: typewriterFont;
}
font-family defines the name of the font "typewriterFont"
src is the path to the typewriter.ttf font file
