Having Trouble with making Nav bar on code pen

Hello,

I was starting the portfolio page project when I encountered problems with making my navigation bar with bootstrap. The nav bar items on the right keep being listed downwards instead of the traditional sideways. I could really use the help.

Thanks

Hey ! Check the link given below. It worked well for me. Tell me if you face any problems with that. I am about to complete my portfolio page.
