I found this code through Google Developer Tools:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" class=" js canvas canvastext geolocation crosswindowmessaging websqldatabase no-indexeddb hashchange historymanagement draganddrop websockets rgba hsla multiplebgs backgroundsize borderimage borderradius boxshadow opacity cssanimations csscolumns cssgradients cssreflections csstransforms no-csstransforms3d csstransitions video audio localstorage sessionstorage webworkers applicationcache svg smil svgclippaths no-opera no-mozilla webkit fontface"> </html>
and this code through the html source code:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> </html>
obviously these classes are generated using Javascript. But why? Why are there so many css classes for the html root element?
