Moving the wireframe over to webflow, I have a few questions:
In relation to 3. You can remove the padding-section-large class and add the padding-section-small class. You can also edit the padding-class-large to reduce the padding, but I wouldn’t recommend reducing it to any less than the padding-section-medium
2. Adding margin-bottom allows elements such as h1 or collection-list-wrapper to be repeated across different pages without all having the same bottom margin. If you added it to the element itself it would change the element’s style everywhere that it appears
Basically every element is as modular and granular as possible. That way you can style specific elements or elements within components without affecting other elements that share the same classes as Emily said.
