Known issues

  • no support for pseudo selectors
  • UTF-8 charset is not always detected correctly. Make sure you set the charset to UTF-8 using the following meta-tag in the head: <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />. (Note: using <meta charset="UTF-8"> does NOT work!)
