for how i did my fonts i went to google fonts and found 2 i liked. and used the @import to add them to my profile.
below i included the code im using for that i change out my font regularly due to boredom or it just doesnt go with what my page vibe is at any given time
@import url('https://fonts.googleapis.com/css2?family=Bad+Script&family=Marck+Script&display=swap');
p{
font-family: 'Bad Script', cursive;
font-size: 150%;
}
h1,h2,h3,h4,h5{
font-family: 'Marck Script', cursive;
font-size: 200%;
if you're currently learning your base text is under the p tag and headings are under the h tags.
hope this helped a little
