Product Page Small Alignment Issues Advice

I am done the project expect the flexbox is giving me issues. It is being used as the Technical Specifications/ spec section. I can not get it to center on the page. Also if you see anything else that could use improvement please let me know. Thank you everyone!!

I will leave a comment in the code to help you guys find it easy.

Looks good, and it’s timely for me since me and my wife have been researching to by some hybrid bikes lately. I’m not sure flexbox is the best choice for your technical spec section. I would look into using grid instead. https://css-tricks.com/snippets/css/complete-guide-grid/
