How to hide the medium input box and only show the text when read-only

I have this working on text inputs, however it will not work on DMX medium editor text areas

input:read-only, textarea:read-only {
background-color: transparent !important;
-webkit-box-shadow: none !important;
box-shadow: none !important;
border: none !important;
outline: none !important;
color: white !important;
}

Also for some reason the Medium Text Editor will not goto read only, like the other inputs.
Am I missing some thing here
Any help would be appreciated

@Teodor any ideas on this ??
