It should be said that the expression-based solution improves the 
initial rendering, but slows the page considerably afterwards, since the 
CSS expressions are recalculated continuously. The expression rules 
could be removed after initial rendering to improve performance, but 
then it wont work if the repeat attribute is added to an element 
dynamically. So its not the perfect solution.
