Are There Particles Smaller Than Quarks?

i was just wondering if there's anything smaller than a quark because as far as i know up, down, anti-, etc. quarks make up the universe.

I believe the Standard Model currently treats both quarks and leptons as pointlike.

This should be moved to the Particles section.

An electron is a fundamental particle. There are no quarks associated. At least, that's my understanding.
