FTM Tantrum Help please

My son is 16 months old and I don't know what to do... Whenever he cant get his way or I walk into another room he throws a tantrum.

His Tantrums include him kicking, screaming, yelling, stomping, banging his head on the floor and kicking the walls.

I feel so undefeated

Idk what to do... I try to ignore it but it seems like it just gets louder.

Half of the time Idk why he is screaming

I talk to him in a calm voice

I even try redirecting nothing works
