HWL> No, there isn't. It's a good idea, though. How about:

HWL>  IMG { width: 1.5 }

I wonder how that works in existing browsers...
Aha, in Quirks mode this value gets interpreted as pixels, in
Standards mode it gets ignored. And Opera 6 always uses Quirks.

I read somewhere that the rationale for not using percentages related
to the container for fonts, was that the percentages would become
really small. If you use factors, the values whould be even smaller :)
