Description Roland Steiner 2009-05-12 15:02:50 PDT
<div style="border: 4px dotted black; height:100px; width: 100px"></div> results in different render output on Safari, Chrome and Firefox browsers (different corner styles, different dot styles).

CSS spec says that "dotted" should be "a series of round dots", so Firefox is more accurate in that regard:
<http://www.w3.org/TR/css3-background/#the-border-style>

It also says "Implementations are encouraged to choose a spacing that makes the corners symmetrical", so Chrome/Safari are better there.

Is there any hope for this bug being fixed? Dotted line means round "dots". It's not a dashed line as rendered in WebKit.

Martin is taking care of this on Qt port, a patch is coming soon :)

I'm interested in fixing this. And in adding a value to border (and everywhere) to accept short dashes as well, so authors have the option of round dots or tiny squares. That would be useful.
