Hello, Thanks a lot for your help. But when opening your test-page in Firefox, the &OverBar still doesn't stretch. It seems a bit longer in the good case (I am attaching the result in Firefox). Do you have any idea why this is happening? Many thanks for your help!

Maybe it doesn't matter in your context, but #x203E; is a lot more portable.

However, you have to be careful. If you put in an extra mrow about the OverBar, then Firefox won't stretch it anymore.

This looks like a bug in Firefox. Specifically, the implementation of "embellished operators" is wrong, since the wrapping mrow should have no effect on the stretching of the bar, though it obviously does. > > I've appended my test page below. > > --Robert > > Robert Miner > Vice President, Research and Development > > Design Science, Inc. > 140 Pine Avenue, 4th Floor > Long Beach, California 90802 > USA > Tel: (651) 223-2883 > Fax: (651) 292-0014 > robertm@dessci.com > www.dessci.com > ~ Makers of MathType, MathFlow, MathPlayer, WebEQ, Equation Editor, TexAide ~ > > ============== > > <?xml version="1.0"?> > <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN" > "http://www.w3.org/TR/MathML2/dtd/xhtml-math11-f.dtd"> > <html xmlns="http://www.w3.org/1999/xhtml" > > <head> > <title>A MathML template</title> > </head> > > <body> > > <h2>MathML Example</h2> > > <p>Buggy case:</p> > > <math xmlns="http://www.w3.org/1998/Math/MathML"> > <mrow> > <mover> > <mrow> > <mi>x</mi> > <mo>+</mo> > <mi>y</mi> > </mrow> > <mrow> > <mo>‾</mo> > </mrow> > </mover> > </mrow> > </math> > > <p>Good case:</p> > > <math xmlns="http://www.w3.org/1998/Math/MathML"> > <mrow> > <mover> > <mrow> > <mi>x</mi> > <mo>+</mo> > <mi>y</mi> > </mrow> > <mo>‾</mo> > </mover> > </mrow> > </math> > > > </body> > </html> > ==================================== > > > -----Original Message----- > > From: www-math-request@w3.org [mailto:www-math-request@w3.org] On Behalf > > Of Christine Müller > > Sent: Monday, November 12, 2007 3:21 AM > > To: www-math@w3.org > > Subject: Question to pMathML > > > > > > Dear all, > > > > I have a question on how to present an "overline" in the following term: > > I have tried "¯" and "‾" but both only result in a single "-" > > overline, but I am looking for an overline that automatically stretches > > across the whole term.
