My browser, Firefox 3.6, seems to display the Mathml equations in the W3C test

  • 0

My browser, Firefox 3.6, seems to display the Mathml equations in the W3C test suite just fine. But if I copy the code into my webpage, like from here, all Firefox produces is something like x y x y instead of how it correctly rendered the W3C page. What am I missing here>

EDIT: I just tried it in Chrome and Chrome failed the test itself by rendering it as x y x y. Needless to say, it rendered the math in my own webpage the same.

EDIT 2: I tried it on a new html document. Doesn’t work:

<!DOCTYPE html>
<html lang="en">
  <head>
    <title></title>
  </head>
  <body>
<math display="inline" xmlns="http://www.w3.org/1998/Math/MathML" mode="display">
  <mfrac>
    <mi>x</mi>
    <mi>y</mi>
  </mfrac>
    </math>
    <math display="block" xmlns="http://www.w3.org/1998/Math/MathML" mode="inline">
  <mfrac>
    <mi>x</mi>
    <mi>y</mi>
      </mfrac>
    </math>
  </body>
</html>

I swear the W3C equations render just fine though…

    Putting your file in a filename named mml-prb.xhtml works. Note the extension.
