I'm also interested in being able to change the background color for alerts. Users are complaining that there's not enough contrast between old and new alerts. I've fiddled with colors but can't figure it out. Any ideas?
and can I add more than one variation of that code so i can create 4 custom background colors for my notices?
I'm trying to learn how to do these simple (seems simple to someone who know's what they're doing but it seems like Greek to those, like me, who are novices). I want to learn. I just need a little help.
