The best method for using google fonts is to include the script include in your index.html file’s <head>...</head> section. You will find as you dive deeper into coding with Google as your friend that one of the best parts is their cdn is built to be supported in this fashion!
The equivalent script include is:
<link href="https://fonts.googleapis.com/css?family=Muli:400,700" rel="stylesheet">
Which is similar to how Google’s Material – Icons work too!
To use this in your style sheets, include this in your base styles.css file:
html, body {
font-family: 'Muli';
}
note: you will find the css tag “font-family” actually has TONS of options. This is the most basic, but if you’d like more information I’m happy to update the answer to be more specific. I want to try to do the best to understand your problem, solve it, and we can make a solid understanding of the problem together.
