css and html editing in Upfront

Using Upfront based loosely around the Gillie theme.

I have another site running Scribe that has some nice social buttons coded in the footer.

It might seem like a daft question but I am a beginner so forgive me- I'm wondering could I paste this code into a code element positioned in the footer of serasongs and edit the urls?

I have tried to do this but it doesn't work.

My problem here is that, although I'm willing to learn by experimenting and reading around, progress is slow and most online resources are not targeted at people who know next to nothing about html. Thanks
