css classes for html root element?
i found this code via 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 开发者_StackOverflow中文版via html source code:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> </html>
obviously these classes get generated with Javascript. But Why? Why so many css classes for html root element?
These get generated by Modernizr, as a means to identify what features are available to a user's browser.
