Fixed some multiple class tags for content blocks. Changed the method for hiding the showing tooltips, instead of display none to display block, they are just opacity 0 and then transitioned to opacity 1. This allows transitions to work (since they are not supported when the display none method is in effect)
Added IE 6/7 support for opacities
