    javascript - css classes for html root element? - Stack Overflow

    i found this code via Google Developer Tools:

    <html xmlns="" 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 via html source code:

    <html xmlns="" xml:lang="en" lang="en"> </html>

    obviously these classes get generated with Javascript. But Why? Why so many css classes for html root element?

    Reset to default 15

    These get generated by Modernizr, as a means to identify what features are available to a user's browser.
