alpha opacity and behavior: url(iepngfix.htc); not working in IE6

问题

.idioma_es #logosFooter, .idioma_es #logosFooter li a {
    background: url(../nImg/microsites/logos/logos_footer.png) no-repeat scroll left top transparent;
    behavior: url(../../nJs/iepngfix.htc);

}

Result in Firefox:

Result in Internet Explorer 6 (Based on IE Tester for Windows):

the path of the .htc file is correct !

Any idea what i'm missing?

回答1:

Don't test this with IETester. It's not completely reliable.

You should use a virtual machine, but you can quickly test a page with http://ipinfo.info/netrenderer/.

After Googling a little, I might have been a little unfair to IETester (though I still don't trust it).

Known problems and limitations :

• CSS Filters are not working correctly in user mode : A solution is to launch IETester as admin user and CSS Filters will work.

回答2:

You can try PIE - http://css3pie.com, that is working in IE6 too.

回答3:

IE6 does not support the alpha channel for background images apart from in specific circumstances. There is no general fix, as there is for foreground images.
