Tribute Page complete...I hope

This was a little rough for me because I did not understand bootstrap as much as i had hoped before starting this project. It originally looked fine in my codepen editor and submitted it without checking it out on other devices. Turns out my page was not very responsive and my elements stacked on top of each other.
Hopefully this time it works out. Please, any advice or critique would be much appreciated.

Thank you,
