### Link to the page

### Steps to reproduce

Logged on the fun five facts website. After scrolling the page on the third section I identified that the facts were numbered instead of being bullet points as specified in the requirement.md

Open the linked fun five facts website and read requirement.md, then inspect the third section containing the Birmingham facts. Change the numbered presentation to bullet points and verify the rendered page matches the requirement.
