[TYPO3-core] RFC #8070: Feature: CSS styled content / scalable rendering of images

I'd like to see typo3 beeing able to use any dimension unit for any size 
value, like:

width = 50%
space = 1em|1em

so a parser determing the unit and calculate the rest based on it. To 
get that working you would of course need to define pixel based 
reference values for every unit.

wouldn't be that difficult I think. Have a look to the dev-list where 
"grac" asked for the feature of this patch (topic:  [Fwd: Re: text/img 
and img elements with css-class?]). In my answer/question in this topic 
from some minutes ago I wrote some thoughts on how a support for 
something like on the barmer website could work.

yes - using % for image scaling would really be something nice. Much 
better than the em-concept that doesn't convince me at all.
