They aren't because the warning has both background and text color set
but they may not be as distinguished on some backgrounds.

Yes, with HTML you typically don't have a working site to start from,
unlike KDE theme authors you have to start from scratch. That's
probably why many people are surprised that a site that works for them

You are wrong on this one. Exactly because the current rendering
engine is complex making even simple changes to it has unpredictable
results. That's why fixing anything on it takes ages.
