Html sample below: <!DOCTYPE html> <!-- saved from url=(0026)http://www.opera.com/about --> <html lang="en"><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <meta name="description" content="Opera is an independent Scandinavian company that's been in the business of making web browsers since 1994.
