IE9 border-radius and background gradient bleeding

Question

IE9 is apparently able to handle rounded corners by using the CSS3 standard definition of border-radius.

What about support for border radius and

Answer 1

Using compass and sass you can easily achieve this like so:

@import "compass";
#border-radius {
@include border-radius('RADIUS'px); }
#gradiant{
$experimental-support-for-svg: true;
@include background-image(linear-gradient('COLOR') %,('COLOR') %,...; }

Compass will generate a SVG image for you.

like so:

#gradiant {
 background-image: url('data:image/svg+xml;base64,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');

#border-radius {

  -webkit-border-top-right-radius: 8px;
   border-top-right-radius: 8px;
 -moz-border-radius-bottomright: 8px;
  -webkit-border-bottom-right-radius: 8px;
  border-bottom-right-radius: 8px;

}

Answer 2

IE9 handles border-radius and gradients together properly. The problem is that IE9 renders the filter proper in addition to the gradient. The way to properly solve this is to disable filters on the style declarations that utilize the filter property.

As an example on how to best solve this:

You have a button class in your main stylesheet.

.btn {
    background: linear-gradient(to bottom,  #1e5799 0%,#7db9e8 100%);
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#1e5799', endColorstr='#7db9e8',GradientType=0 );
}

In a conditional IE9 stylesheet:

.btn { filter: none; }

As long as the IE9 stylesheet is referenced in your head after your main stylesheet this will work perfectly.

Works for me...

<!--[if gte IE 9]>
  <style type="text/css">
  .gradient{
   filter: ;
}
</style>

css

border-radius: 10px;
background: #00a8db; /* Old browsers */

Answer 4

I decided to disable IE9 from rounding corners to workaround this bug. It's clean, easy and generic usable.

{
border-radius:10px;
border-radius:0px \0/;
background:linear-gradient(top , #ffeecc, #ff8800);
/* ... (-moz -ms,-o, -webkit) gradients */    
filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0,startColorstr=#ffeecc,endColorstr=#ff8800);
}

filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#4f81bd', endColorstr='#8abbd7',GradientType=1 ); /* IE6-8 */

Was doing this to me and once I removed the "filter:" line the bleeding went away. Plus I use PIE.

Quick IE Shadow Fix:

fixBoxShadowBlur($('*'));

function fixBoxShadowBlur(jQueryObject){
if($.browser.msie && $.browser.version.substr(0, 1) == '9'){
    jQueryObject.each(function(){
        boxShadow = $(this).css('boxShadow');
        if(boxShadow != 'none'){
            var bsArr = boxShadow.split(' ');
            bsBlur = parseInt(bsArr[2]) || 0;
            bsBlurMeasureType = bsArr[2].substr(("" + bsBlur).length);
            bsArr[2] = (bsBlur * 2) + bsBlurMeasureType;
            $(this).css('boxShadow', bsArr.join(' '));
        }
    });
}

}
