Many fossil fuels are gaseous at STP. One example is methane.
Natural gas is a fossil fuel consisting largely of methane (CH4).
The term "fossil fuel" is not a category of matter, but just how that fuel became the way it was. It refers to any substance which can be used as fuel and which originally came from living matter (such as prehistoric plants). It is false that all methane is a "fossil fuel" since only methane deposits that exist as a result of fossilization of plants and animals that died millions of years ago is a fossil fuel. Other methane is not. Methane created in any other manner is not a fossil fuel.
Coal, methane gas, oil are fossil fuels; uranium is not a fossil fuel.
