I understand Diels-Alder Reactions, but I can't seem to figure out the mechanism for this problem...
I don't get how the bridge forms and which carbons are involved...
Can anyone please help?

My best advice is to youtube it. There are A LOT of videos up there, some by chem professors that will explain in detail everything you need to know. It would also help if you posted the problem 🙂

The carbons that do not have double bonds end up on top forming a bridge.

The 2 carbons without the double bond are pushed up. dlene gives 4 carbons, dienophile gives 2 carbons.
