Customise Header Message with CSS

We’re currently getting a lot of user queries regarding switching/ unenrolling from ILT sessions due to those options being hidden in a menu right out of the way. I was hoping to use the Header Message to highlight a resource showing people how to switch sessions as a way of reducing this. However, the header message itself is completely unformatted with no way to do so in the settings. I tried editing it with CSS but nothing I try seems to work.

Here’s where I got to:
 

app-layout-header-message {
background-color: #a11fff;
color: #ffffff;
padding: 10px 20px;
text-align: center;
}

Has anyone managed to do this successfully?

try it with this. I think you have the wrong container:

lmn-expandable-content .expandable-content.expandable-content-clamped { /* the element was section.expandable-content.expandable-content-clamped */
color: crimson;
font-style: italic;
font-weight: bold;
}

you should be able too add other styling elements once you get it working.
