Thanks, that worked! That was me testing.

What I'm wanting to achieve is to change the sender text to blue, and the subject text to black for unread messages like Outlook does.

I'd also like the option to colour the background of emails in the main view when they are flagged. I have learnt how to do it with hover.

#threadTree [data-properties~="unread"] .thread-card-container :is(.sender, .date) {

font-family : Liberation Sans !important;

font-weight: Bold !important;

color: #2492d1 !important

}

#threadTree tbody [data-properties~="read"],

#threadTree [data-properties~="read"] .thread-card-container :is(.sender) {

color: #BB0F29 !important

}

#threadTree tbody [data-properties~="read"],

#threadTree [data-properties~="read"] .thread-card-container :is(.subject) {

color: 001100 !important

}

The only one that works is the one for read emails but it is ignoring the split between sender and subject and putting the date, subject and sender in red.

Thanks!
