social media widget

[MeridenLibrary]

Hello,
This may be more of a wordpress question, but I am trying to get the social media widget to work correctly on my site. www.meridenlibrary.org

I tried to pub multiple social sites in one widget but then they were all the same color. So I tried to put one social site in individual social media widget and then the others didn't work or look right. Right now, it is messed up. If some one could look at it or tell me what I am missing. I will leave the site as is for now, but should change it soon.

Thanks!
