Help needed regarding formatting of the music player tile

Is there a way to hide the volume percentage from the music player tile? It stays by itself in a div element with neither an ID nor a class assigned, therefore i can't find a way to refer just to it when applying CSS formatting.

I finally managed to do it by using the :not() pseudo-class. In the end i decided to hide everything except for the play/pause and mute/unmute buttons. The lines with the CSS code that did the trick can be seen below.

.playing div:not(.muteControl, .play-pause) {display: none;}
.stopped div:not(.muteControl, .play-pause) {display: none;}
