bug - MS gradient fails in IE8 strict mode

#1 (**permalink**) 10-23-2009, 12:00 PM

The custom Microsoft Gradient filter does not display as expected in strict
IE8 mode when the style includes a background color, using Internet Explorer
8.0.6001.18702 on Windows XP SP3. The gradient works in IE7 mode, or if the
element does not have a background color, or if the element is a button.

See the extended example below.

<html>
<head>
<title>Gradient test in IE</title>
<meta http-equiv="X-UA-Compatible" content="IE=8">
<style type='text/css'>
..grad
{
color:yellow;
filter:progid:DXImageTransform.Microsoft.Gradient
(GradientType=0,StartColorStr='white',EndColorstr= 'blue');
background-color:green;
}
</style>
</head>

<body>
<h1>Gradient test</h1>
This is a test for a bug in Internet Explorer 8.
We expect to see a blue gradient instead of a green block in the table.
This works if you change IE=8 to IE=7 for X-UA-Compatible
*or* remove the background-color from the stylesheet.
(You must also allow "active content".)
<table class="grad" cellSpacing="0" cellPadding="0" width="100%" border="0">
<tr height="55"><td>Hello, world!</td></tr>
</table>
Note that buttons have gradient in IE8 mode even with a background color:<br>
<input type="submit" value="Hello, world!" class="grad">
</body> </html>

Rob,

Thanks for pointers -- it was interesting to read about the official
ms-filter syntax for IE8. However, it doesn't solve my problem.

I still think this is a rendering bug in IE8:
1. the button *does* get the gradient, so the style clearly parses OK.
2. changing my example to the blessed syntax
-ms-filter:
"progid:DXImageTransform.Microsoft.Gradient(Gradie ntType='0',StartColorStr='white',EndColorstr='blue ')";
has no effect on the outcome. I think that's because IE8
accepts the old format as "close enough".

So, does anyone know a workaround? Or is there any more direct way to
report this bug to Microsoft? From what I could tell, this newsgroup
is the approved channel, but I still don't quite believe it.

Thanks!

Hi,

You include both syntaxes. If you are pedantic, you also include the syntax
for the other browsers.

style="display:block ; background-color:Red; color:White;
text-align:center;z-index:1;filter:alpha(opacity=00);-ms-filter:
'Alpha(Opacity=00)';opacity: 0.00;-moz-opacity: 0.00;filter:
alpha(opacity=00);-khtml-opacity: 0.00 ;clear:both"

Regards.

Right, I tried that, and it had no effect.

I still get a button with a pretty gradient, and a plain green background in
the table. Even though they're both supposedly displaying the same style.

If it was really a parsing issue as you suggest, shouldn't the gradient fail
to appear everywhere?

I don't know. I am not looking over your shoulder. You are the one holding
the keyboard.

Is you page error free otherwise? Do you have the IE8 compatibility view
error handling switched off?

Regards.

Feel free to try the HTML case that I included with my original post -- it's
one way to "look over my shoulder" from wherever you are. :)

I think the page is otherwise error-free. I'm not sure what you mean my
"IE8 compatibility view error handling", but you can see in the original HTML
that I've explicitly told IE to read the page in IE8 "strict" mode.

The rendering inconsistency goes away in IE7 mode, but that does me little
good. I based my example case on a much more complicated page on which I
also have outlining, a feature that IE8 seems to only support in "strict"
mode. Can't tell if that's a different bug or Intended Behavior, but I've
been assuming the latter.

Thanks for your continued help and attention. Out of curiosity, is there
any more direct way of reporting a bug to Microsoft or is this as good as it
gets?
