Responsive Crowdfunding product page

What challenges did you encounter, and how did you overcome them?

None was that challenging. The only mistake I did was to make the first section as absolute, and this made the responsiveness not that good (in my laptop, it shows correctly, in my computer that has a larger screen, it not).

What specific areas of your project would you like help with?

None in particular. I know that the code is too extensive and I plan to narrow down and create more reusable code for now on. The CSS could be way less code, but that's it. Any feedback/tip will be appreciated!
