I successfully transformed my volume slider from horizontal to vertical using CSS. However, the functionality of the volume slider still behaves as if it were horizontal. In other words, I have to click horizontally to adjust the volume instead of vertically.
HTML
<div class="jp-volume-bar wolf-volume">
<div class="jp-volume-bar-value"></div>
</div>
CSS
.wolf-jplayer-playlist .wolf-volume{
display:none
}
.wolf-jplayer-playlist .jp-volume-bar{
position:absolute;
height: 50px;
width: 5px;
padding:0;
overflow:hidden;
top:85px;
left:278px
}
.wolf-jplayer-playlist .jp-volume-bar:hover{
cursor:pointer
}
.wolf-jplayer-playlist .jp-volume-bar-value{
height: 300px;
width: 20px;
background-color: #db2537
}
Jquery (quite lengthy code):
