I have followed the documentation for adding local fonts (google font ‘Cinzel’) and have got it working on the homepage on desktop and mobile (including off canvas menu when clicked on homepage) but the font is not showing up on any other pages or off canvas menu when clicked from those pages.
the font isn’t loading on any of your site, you’re probably seeing a local version of the font.
If you right click and inspect the browser on your other pages, you will see all the font requests are 404ing – which points to your @font-face CSS has the incorrect URL.
