I know what they are used for, but how do they work?

The salt bridges maintain the neutrality in the two solutions. As electrons flow from the anode to cathode in the wire, the negatively charged ions migrate to the anode half cell using the salt bridges so that the solution in that half does not become positively charged, and vice versa for the cathode half cell.

The salt bridges allow there to be a circuit because without the salt bridge the anode will stay negative and the cathode side will be positive. The bridge allows for the flow to continue

Is the salt bridge composed of anions or cations?

I think its just negatively charged ions, anions, that are transferred in the salt bridge because the point is to more or less "cancel out" the increase in negative charge going in the direction of the current

A common material for salt bridges is KCl. The K+ ions dissociate into the cation tub, and the Cl- ions dissociate into the anion tub to counter charge buildup and allow ion transfer.

The salt bridge is used to complete the circuit by allowing ions from the anode and cathode to transfer.
