I have the following ticket table in which I'd like to hide the ticket ID, yellow highlited.
By inspecting the code, this can be achived as hiding every element with any value specified by the attribute data-test-ticket-id in the span class.
<td>
<div>
<span data-test-ticket-id="2595" class="muted">
#2595
</span>
</div>
</td>
The coded table can be found here: https://jsfiddle.net/f6qkgL54/
I tried td.div.span { display: none !important; }. I think the best method would be using jquery but I have some difficulties.
Edit
I can't use .muted { display: none; } because it is used almost everywhere in the system so it will hide important elements

mutedclass from thetableyou have. I have addedtwo demo span'soutside as well to show that they are not being hidden but theticket ID;'sare not showing anymore.
