How to add social media links on the same line as menu?

Hello,
I am trying to add social media links on the same line as the menu and to the right of the menu. For some reason it is displaying on the next line. When I look at the rendered source on Chrome, I see that the link is outside of the “div” where the menu is, but in the code (masthead.php) I have it inside the end of “div class=”full-container””.
Here is the link – femombeone.com/about/

Thank you in advance for your time and effort in replying.
