Rewriting a Web Page XHTML in HTML5 with CSS3?
I am taking care of a Web Site written a couple of years ago according to xml specifications <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> Is it still necessary to keep this definition? Should I rewrite it completely in HTML5 and CSS3? What do you recommend? Thanks!
