I am starting a website for a client and have custom social media icons at the footer. I am not using the convenient Facebook, Twitter and G+ elements found in Webflow's elements panel because I want to use custom icons. If it is possible to use the WF elements and exchange the default icons/buttons that would be great. If not, how do I actually make these social icons active. I don’t know what to insert in the Link Settings to accomplish this. Any help is appreciated.
