Hey Jochen,
I am not sure I understand what you are trying to achieve? Are you intending to assign the uk-table style to table. If yes, this is not possible as far as I am aware.
Thanks,
Yes, exactly.
I thought that is possible with the LESS mixins: http://lesscss.org/features/#features-overview-feature-mixins
I don't want to add too much theme specific classes to the daily blog content.
