You see, I'm trying to use the Open Iconic icons. I recommend downloading a folder called open-iconic-master, which I already have, but I have no idea where I install it. Does someone explain to me where I should place that folder in my project so I can use these icons?
I fixed it. I used this:
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-beta/css/bootstrap.min.css" integrity="sha256-m/h/cUDAhf6/iBRixTbuc8+Rg2cIETQtPcH9D3p2Kg0=" crossorigin="anonymous" />
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/open-iconic/1.1.1/font/css/open-iconic-bootstrap.min.css" integrity="sha256-BJ/G+e+y7bQdrYkS2RBTyNfBHpA9IuGaPmf9htub5MQ=" crossorigin="anonymous" />
Although, does anyone know anything better? The tutorials on how to use Open Icon are confusing and this was the only thing I found that worked.
