Hi Lotny,
Thank you for writing in!
The custom added fonts won’t be appeared in the Customizer typography sections as it uses google web fonts. However, you can apply any font using CSS to any element in your website. For example, if you want to change the font of the headings, you can simply use the following CSS code under Custom > CSS in the Customizer:
h1, h2, h3, h4, h5, h6, .h1, .h2, .h3, .h4, .h5, .h6 {
font-family: 'Walkway black';
}
Hope this helps. 🙂
Thank you.
