Iamrunda I've seen people write code, but I don't know where to write it，i change the settings ，but No effect, i write the tag with class or write class only ,but don't take effect i don't know how to change the icon
luceos Iamrunda fab is the prefix for brands actually. I think the free icons are usually in far for regular and fas for strong. Light fal are premium icons that Flarum, by default, cannot render.
girefko Iamrunda Usually you just put fas fa-dog or fas fa-cat You can find all available icons here: https://fontawesome.com/v5/search
