Dasmoto Arts Review and improvement?

Hi, I like that this is more self directed than the previous projects. I had to search and find how to make the end of the paragraphs blue but otherwise, the was very straight forward except for one part.

Is there a way to condense the code that holds the 3 different background colors for the products? I created ID’s for each which kind of defeated the purpose of creating one class for all of the products. Maybe I’m asking for something that hasn’t been touched on yet but I’d like to know if it’s possible. Thanks
Here is my Git repo for both HTML and CSS files GitHub - Nullified002/Dasmotos-Arts: A simple page editing the colors of things at the beginning of a Codecademy course.
