Hi you can locally add the font and activate it in html or you can post links to fonts online.
example:
<link href="https://fonts.googleapis.com/css2?family=Orbitron&display=swap" rel="stylesheet">
<style>
@font-face {
font-family: Electronica-Normal;
src: url(custom_font/Electronica-Normal.otf) format("opentype");
}
</style>
