How to use my own fonts?

If you have a font in your ftp, then you can use that by putting a font-face into your themes/templates style.css, or into some css file, which is loading in your frontend. These are usually not loading in the backend, so always check the frontend, if it's working fine. The css code, which you can use is this:

     font-family: ExampleFont;
     src: url('');

Change the src to your font's link, and the font-family to something better, and then you can go to the Smart Slider's SettingsGlobal font or your slider's font → Pick a font → write ExampleFont or your font's name into the font family, and your font will be on those texts, where you choose it.
