How do I change the font on my whole profile??

<style>

@import url('YOURURLGOESHERE');

</style>

<style>

:root {font-family: 'NAMEOFYOURFONT', sans-serif;}

h1 {font-family: 'NAMEOFYOURFONT', sans-serif;}

</style>

The URL should look something like this: "https://fonts.googleapis.com/css?family=Indie Flower". Make sure you've DOWNLOADED the font and spelled everything correctly!
