social menu doesn't respond to styling in css

The Brink Hi, I've moved the following icons from my main menu to the Social Menu as I was them to be independent. Only thing is they now do not respond to any styling I'm trying to put on them. Also they look quite different from the ones that appeared on my main menu. Here is a screenshot of what they used to look like (circled in red) next to what they look like now (circled in green). I actually like the new icons better, I just need them to be bigger as they are barely legible. Cheers TB
