Admin Forum:Underline, strike classes

Because Wikia upgrade is drawing near and the and    tags are no longer used in HTML5, I need to create CSS replacement for those. Can you help me? I need information what is needed to be added in the style sheet and later - how to use these classes in the article. Also, what about tags? Will these be also deprecated? Thank you in advance, Final Cannon 19:50, July 15, 2012 (UTC)
