From time to time I see questions or answers in which the poster has used something other than regular font size. This can look absolutely appalling. e.g. https://serverfault.com/questions/270065/stop-an-already-running-cron-job/273477#273477

Can the CSS please be adjusted so that such posts don't look like someone screaming at the top of their lungs?

**Edit:**

Mark's comments regarding the sample I linked are perfectly correct but sometimes people <h1>use the H1 tag</h1>
which looks every bit as bad.
