Jerry Garcia Tribute Page Project Feedback!

Hello! I am new to freeCodeCamp and fairly new to coding as well. I just completed my first project, a tribute page to Jerry Garcia and his musical career. There is only one thing that is bothering me and that is trying to get the dates better centered over the top of the timelines. If anyone has any advice for this or would like to look it over and give me feedback it would be much appreciated!
