Price Grid solution

So for this challenge I tried something a little different, I usually style each part of the page one at a time starting from the top down. This time I tried to make classes CSS then adding multiple classes in HTML to each part to gain the style I desired. Usually I only have say 1 class per div and I style everything on that 1 class but this time I made classes for the different margins and added them to the desired elements etc... It actually felt better because normally alot of the code I write for each element would be repeated for the next item I styled, but this allowed me to write this on a seperate class and just add that class to multiple elements in HTML. Any tips or advice for things to look into would be amazing. Thanks for checking it out!!
