Hello from France (and sorry for my bad english),

Congrats for CSS3Pie witch is a very good tool !

I discovered a little bug with the border-image emulation on Internet Explorer : it seems that PNg transparency doesn't work on IE, even on IE8

Here's an exemple :

Did I miss something, or done something wrong ?

Have a nice day,

Raphaël

Thanks very much for the excellent testcase!

I don't think this is an issue with transparency. The PNG transparency seems to be getting rendered just fine. However there are some other issues making it look bad:

1) There seems to be a PIE bug where it still tries to render the solid border even when border-image is specified, whereas it should discard the border. I've opened ticket http://github.com/lojjic/PIE/issues/issue/51 to get that fixed.

2) For your second demo, it is missing the 'fill' keyword to tell it to fill in the center of the border-image like a background. The CSS3 spec requires this keyword, though other browsers don't seem to enforce that yet. PIE follows the spec.

3) On the paragraphs I see the top-right and bottom-right slices are shifted to the right by 1px. This looks like a PIE bug; I've opened ticket http://github.com/lojjic/PIE/issues/issue/52 to track it.

Those are the issues I see. Is there anything else you've found?

OK, actually neither Mozilla nor Chrome understand "fill" keyword (in my tests), so I have to write the code so to work :

-moz-border-image: url(tab.png) 0 45 stretch;
-webkit-border-image: url(tab.png) 0 45 stretch;
border-image: url(tab.png) 0 45 fill stretch;

This seems to work.

Not yet, thank you
