Responsive React JS page with lots of functionality.

Hello, Frontend Mentor community 👋

It is another React JS challenge of mine. This time I tried to create something really cool with lots of bells and whistles. However, I think I went too far with it: my code turned into a complete mess, and the site itself started working somewhat slowly. Anyway, at least, everything is working without bugs, as far as I can see.

❗ Aside from the smoothness, I ran into a few other problems:

• In Chrome, the menu text (in the pledges' popup) gets quite blurry, and all the solutions I tried (like transform: tranlate3d(0,0,0) or scale(1), etc.) don't fix it.
• Sometimes, images flicker when I launch the site for the first time. I tried to deal with this problem using an extra component called Preloaded, where I preload all the necessary images and then put them in a div with display: none. However, I don't think that's the right way to do that.

Well, other than that, I enjoyed the challenge. It really tested my React JS skills. Besides, I realized many React libraries can help me write cleaner code with less effort. Hopefully, I'll learn their proper use in the future too! 😃

Thank you for your time if you read this post till the end! And as always, feel free to leave any comments! 😉
