[Tribute Page] Stephen Hawking's Tribute - Responsive - Feedback wanted

I created a Tribute page to Dr Hawking and wanted to try and make a responsive timeline. You can click the down chevron in the hero to automatically scroll to the timeline. The timeline is responsive (mobile first) and starts in a single column on small displays with the dates on the right and the content on the left, on larger screens the dates will be in the middle with content alternating sides, left and right.

You should try resizing to see it working.

Just looking for a bit of feedback on how it can be improved (other than the fact I’m not a designer).
