Hello on my Site https://das-schiefe-haus.de/portfolio-item/alles-inklusive-fuer-sie i insert some Icons from https://fontawesome.com/icons/ but some of them are not displayed. How can i display that icons? Is https://fontawesome.com/icons/ the korrekt site for searching Icons? If not, how/where can i search icons for example a “cup” or “parking sign”?
