Clipboard landing page using SASS

In the first section "Keep track of your snippets" i did not find a way to have a nice responsive design, on some viewports width it does not look good at all. I had to fix the width of the text on the right to make it okay-looking but I don't like that.

Also I used the facebook , instagram and twitter in img tags, blocking me from having a hover effect to switch colors. I don't know if there is still a way to do so in this situation. Or if I should have searched and used the ones from Font Awesome.
