Why does capacitor block DC and allow AC

In the case of AC voltage. When AC voltage is connected with a capacitor, one plate of the capacitor gets charged positively and the other gets negatively charged. Later when the direction of AC current changes, the capacitor will change its direction, and thus will get discharged. This process continues in the case of AC voltage.
