Re: [css3-font] Extension of font-stretch property

I understand that distorted fonts are not ideal, but I think that should. Just be an expected caveat of using them. As a designer, if I ask for a condensed font, then I expect it to be narrower than a non-condensed version, even if that means synthesizing when condensed versions of the typeface are not available (which I also expect to be far more common on the Web).

It will be happy to Latin font families which have a various type of condensed or expanded font. When a font does not exist for a given width and is scalable in size, it will be useful the font-stretch gives a ratio of scaling in the inline progression direction. For scalable fonts, the font-stretch is a scale factor applied to the EM unit of the font. Values have the following meanings:

If the parent element's ratio is not close to a table entry, the user agent is free to interpolate between table entries or round off to the closest one. The user agent may have to extrapolate table values if the numerical value goes beyond keywords.
