Hyperlink Color and Style Change; Removing an Icon from Social Icons

Hello,

I have two questions. I am using the Text widget in WordPress for my sidebar and would like to have a hyperlink in the section that is bolded. I don’t want any of my other links (such as my menus) to be affected.

So, for example, I would like “Here is some information” to be the ONLY thing hyperlinked with a bold font and different color (blue):

Blah Blah
Blah Blah
Here is some information

Second question. I have my RSS feed in my Social Icons settings, and therefore it shows up in both the floating top bar and my sidebar. Is it possible for me to remove the RSS icon from the sidebar only?

Thank you.
