Login to Adobe Fonts and create your typeface web kit. Copy the code generated, it should look something like this:

<link rel=”stylesheet” href=”https://use.typekit.net/uko8kns.css“>

Back up the code in the header.php file. Then paste this into the header tag of your header.php file.

Add custom CSS file (Appearance > Customise). Here is an example:
