Understanding CMOS Inverter Behavior: V_i=L and V_i=H Explained

[MissP.25_5]

Hello.
Can someone explain to me what does $V_i=L$ and $V_i=H$ mean in CMOS inverters?

Does V_in equals a logic LOW signal, and V_in equals a logic HIGH signal, fit the context? The allowable voltage range of each level is dependent on the supply voltage. Remember that CMOS can operate over a wide range of supply voltages.

I just found the answer! Yes you are right. Vin = L= 0v and Vin=H=Vdd
