This is somewhat off-topic...

I had to create some some button classes for the types of buttons (messages really) that I display and one of them is a notification that the driver in the 301 needs to re-fasten their seatbelt. Since this is a safety concern, we want to make sure they don't ignore it, so it blinks (really changes colors) at them until they put the safety belt back on.

Yes, that's right, I've created the equivalent of the blink tag for LFS. And yes, that does make me feel queasy.

ok, then the next thing would be a <marquee> button which dances around on the screen from left to right ^^
