Change the Fonts Globally with the Customization Feature.
Here are the steps
Steps 1 = There are two ways to get to the Customize option in WordPress: Logging into the WordPress Dashboard > Clicking on Appearance > Customize, or by logging into the WordPress Dashboard > Clicking the Site Name in the top left of the menu bar > then clicking on Customize in the top bar.
Step 2 = In the menu bar at the top of the page, click on Customize.
Step 3 = Scroll down until you find the option for Additional CSS. Click on this option to proceed.
Step 4 = Scroll down the left-hand side of the page and find the field to add the additional CSS code. Click in the field and then add your font family code. Here’s an example of the code you can add:
* {font-family:"Courier New", Courier, monospace}
The ( * ) in the CSS code will apply the Font style to all text on the website.
Step 5 = Your font will immediately change when you paste in the correct code. In order to save your changes, you will need to click on the blue Publish button in the Customize menu column.
I hope its works for you.
Thanks.
