It happens that in many fonts this is close to or the same as the width of the M, and that gave rise to the name, but they are not guaranteed to be the same. > So, it would be possible to create a font > with a letter 'M' that has an absurdly large height.

Better to use ex, the x-height, which seems more likely to be font-specific, although I didn't check the CSS spec for it.

Well the definition for the 'em' unit is the size of of the capital letter M in the current font. So, it would be possible to create a font with a letter 'M' that has an absurdly large height. Then you link the font to the page, and create a div with a height of 1em. The pixel size of the div should match the the height of the absurdly large 'M' (provided you use the right font height). Not a perfect solution, but its better than nothing. -- Aaron http://sachimp.com http://getcorkd.com signature.asc Description: This is a digitally signed message part
Re: [OpenFontLibrary] font face firefox friendly?
Hi, everyone,
It would be nice if there were a way to query the browser (using
Javascript) about whether web fonts are supported or not. If that
were possible, then a web site like the new OFLB site could
dynamically show the web font preview when supported, and hide it from
view when not supported.
The Javascript would be trivial to write but my investigation so far
has not revealed any way of detecting web font support.
It is a common "best practice" principle when coding in Javascript
nowadays to check for the existence of certain properties. If the
property exists, then we can exploit the functionality whose presence
is implied by the presence of that property. If not, we can code
around it.
So perhaps we need to encourage the browser developers to expose a
public property, or document such if it already exists:
if( thisBrowser.supportsWebFonts ){
myWebFontDiv.style.display="block";
}else{
myWebFontDiv.style.display="none";
}
While I agree that the new OFLB site needs to rally toward the future,
unfortunately it looks clunky to say "The text to the right should be
rendered in Font_ thanks to web font linking with @font-face. If
you see a monospace font, your web browser probably does not yet
support this new web technology."
On my laptop, I see DejaVu Mono Sans used in FF 3.0.5 for the
unsupported @font-face preview. The problem is, unless I look very
closely, I might actually think that I *have* got a preview of
"Font_xxx" --especially if "Font_xxx" is some kind of sans serif font
(like Puritan, for example)!
If someone on this list has any ideas on how to check for @font-face
support using Javascript, please let all of us know about it.
