How to remove the “Powered by Google” logo in the Google Map Autocomplete dropdown list?

Animesh Nandi‘s answer is a bit old.
Actually, to remove the ‘powered by Google‘ logo I had to use the following code:

.pac-container:after {
    /* Disclaimer: not needed to show 'powered by Google' if also a Google Map is shown */

    background-image: none !important;
    height: 0px;
}
