After researching numerous answers, I am still unable to identify what I may be doing wrong. I have designed a collection of custom fonts using iconmoon, and after downloading the css and font files, I uploaded them to a directory on my website. I am attempting to reference the font.css file in an Ad on eBay, but it simply does not work. Interestingly, when referencing Iconmoons development font.css file, I can see my Icons without any issue. Any insights or suggestions would be highly appreciated.
