In our WordPress themes, you can embed Google Fonts to the Appearance > Customize > Typography Settings section.

When you add the Google Fonts, make sure to only add the URL portion, like this: https://fonts.googleapis.com/css?family=McLaren

Then, you can use that font in other typography fields, such as Font Family for Headings & Widget Titles, by entering the name of the font, which in the above case would be: McLaren

You can also make use of that font in your text editor by adding the necessary HTML tags, such as <p style=”font-family: McLaren;”> or other tags.
