Any feedback for my portfolio page?

Hello !
I just started out free code camp and went through the first few challenges pretty quickly since I already had some knowledge in html and css. I am now working on my portfolio page and I wanted to know what you thought about it. I tried using bootstrap to make it responsive but at some point I gave up because it got too hard. Here is the link : https://codepen.io/Jajalaf/full/MbQRQw/ Also, if anybody could help with the form, I would be very grateful because I don’t really know how to make it work.

Thank you ! :smile:
