Crowdfunding product page

What are you most proud of, and what would you do differently next time?

Hi here is my solution for Crowdfunding-product-page. I used HTML, CSS, JS.

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

It was to display the good page and transfer the information in order to modificate the data on the main page.

Reach different parent and child nodes

arraySelect[i].firstElementChild.firstElementChild.classList.add('button-project-click');
arraySelect[i].firstElementChild.childNodes[3].style.color = '#3CB3AB';
arraySelect[i].parentElement.style.border = '0.15rem #3CB3AB solid';

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

It's to have some tips to improve my JS and have more readibility and shorter code.

Thanks.
