Hi I am currently doing the Random Quote Machine project and I have run into a problem using the font awesome twitter icon. When I use it or any other social media related icon in my code, all I get is a square. If I try using a search icon or heart icon everything works fine. Any ideas?
Here is the Codepen link: https://codepen.io/sam_donaldson2018/pen/OqBvvq
The icon in question is coded on line 46 in the JS editor.
