I still couldn't understand why input and output waveforms out of phase with each other in a common-emitter amplifier configuration?

Dear student,
In common-emitter configuration  the output voltage is inversely proportional to the input signal strength. That is, the output voltage decreases as the input signal increases. For this reason, the common-emitteramplifier configuration is referred to as an inverting amplifier. And hence the waveforms are out of phase.
Hope this helps.
Thanking you
