Default What exactly is a gas planet?

I keep hearing that Jupiter through Neptune are gas planets. What does
that mean? Are they really not solid anywhere?

Thanks

A misnomer harking back to the days when it was thought that they were gas
throughout. The current models consist of liquids in various states surrounding
a rocky metallic core.

The interesting speculation was Jupiter having 'squoze' carbon at it's
core, under unbelievable pressures, into a core of diamond. Fun stuff.
