Below are instructions for changing the fonts in your theme.
1). In your wp-admin, go to Appearance > Customize> Fonts. Leave this page open.
2). Find the Google Fonts that you want to use, and click on the red plus sign next to the fonts of your choice.
3). After doing this, click on the black box that appears at the bottom of the screen that says Family Selected.
4). Now, click on the @Import tab and copy the URL only. This is the “font link.” It will look something like this:
Here is a visual of the “font link” you want to copy:
5). Go back to the theme customizer and paste the font link into the Insert Font Link box.
6). In the text box where you want the font changed (ex: Body Font Name) type the name of the font you just imported. For example, in the Body Font Name box I would type Trirong.
To change the font size, type in your desired font size in the appropriate font size box.
