s/dnline/display/

maybe you want "overflow: hidden" so that you don't have any potential problem with scroll bars.

why this line-height property?

why do you need this 2 seconds delay?

As I said in previous review, I think this can just be centerBlockOffset = (logicalWidth() - contentWidth) / 2; since contentWidth < logicalWidth().
