I am currently using the following code to color page comments for admins:

.comments li[data-user="username"] blockquote { background: #color !important; } .comments li[data-user="Username"] blockquote:after { border-color: transparent #color #color transparent !important; } .comments li[data-user="Username"] blockquote div { background: transparent !important; }

I am looking to do the same for forum and message wall posts/replies. What would be the appropriate syntax?
