CSS Font size in points doesn't match Node.Font.Size

So what is the best approach to dealing with pt sizes in CSS? Do I multiply every pt size by 3/4 in CSS? Will this always result in Node Fonts that are 4/3 times the specified CSS value?
I assume I can't just use px and expect Node Fonts to have the identical value, only in points, regardless of the display.
Maybe Region should have a new attribute called FixCSSPoints that we could set after adding style sheets?
