Messed up rendering of rounded corners in IE9 - css

I'm hunting some very odd rendering issues in IE9 in windows 7. I'm using the microsoft "filter" method wherever there are gradients, it's HTML5, and everything is in standards mode.
Please note, as there has been some confusion: This is happening everywhere there are rounded corners, including in situations where there are no gradients, and even no background color at all. The specific issue can be seen in the screenshots below as gaps in the border and color getting repeated on the x-axis, INSIDE the element.
As far as I can tell, I have set up everything correctly, and of course it all renders just fine in firefox and webkit browsers.
Has anyone ever seen this? I'm chasing my tail and googling turned up squat.
Input box:
DIV with gradient background:
Edit:
The twitter-bootstrap link provided below exhibits exactly the same issues on all their example elements. Smarter people than me are working on that project, so I'm racking this up as un-solvable with CSS alone. Feel free to close.

thats a known bug in IE9 and theres no really easy solution* to get rid of this. the easiest ways would be:
use a background-image containing the gradient instead of a gradient for IE < 10
use a plain background-color instead of a gradient for IE < 10
twitter bootstarp, for example has to deal with this, too. they've chosen to use a plain background-color for their buttons as you can read here:
In IE9, we drop the gradient on all buttons in favor of rounded
corners as IE9 doesn't crop background gradients to the corners.

IE Filters and rounded corners don't play nicely together. You're going to have to choose between a solid background colour or square corners for IE. Vendor prefixed gradients are going to be supported in IE10, so there is that at least.
Twitter make note of this on the Bootstrap site, saying:
"In IE9, we drop the gradient on all buttons in favor of rounded corners as IE9 doesn't crop background gradients to the corners."

CSS3 shadows in IE harden rounded div corners

When I use only rounded corners on my div, it looks about how I expect in IE9.
border-radius: 7px;
However, when I add the following line to make a drop shadow, I get an unexpected effect:
filter: progid:DXImageTransform.Microsoft.Shadow(color='#818181', Direction=135, Strength=3);
Here's a screenshot of the effect. I'm referring to the ugly little black corners suddenly appended to my light blue div:

How can I get rid of that?
IE9 supports box-shadow natively, so there's no need to use the old filter style.
If you're using the filter for the benefit of older IE versions, then it may be that both shadows are coming into play in IE9, and slightly different, thus causing the weird effect.
My first suggestion is simply to drop the filter style. This will mean that versions of IE won't see the box shadow, but it's not really a critical element of the layout.
If that's no good, then I would suggest using CSS3Pie to implement the box shadows for older versions of IE. As a bonus, it'll do the border-radius too.
With CSS3Pie, you can use the standard CSS box-shadow style in older versions of IE, and not need to worry about the filter style. And, to show how it directly answers your question, it will switch itself off automatically in IE9, so you won't get the double shadow effect.
Hope that helps.

browser compatibility issues-css

I am getting this display in IE 7
I am getting this display in Firefox:
for the following code
Could anybody point me, What I should do to make the IE Display simalar to Firefox and also, How Do I make the Size should be same for all the headings?
Internet Explorer does not support gradients, shadows, nor border-radius properties. border-radius is supported in IE9, but this won't be of much help!
You can look into CSS3 Pie, which uses IE-specific .htc files to achieve almost the same effect.
For now, if you really need to be fully compatible with all IE's (and other browsers for that matter) I'd use an image. It's not very nice but at least you can rest assured that it will always work ;-)
Rounded corners and drop shadow aren't going to work in IE7 without a lot of clever image tricks. You can't fix it through CSS alone.
Alternatively you could probably find a JavaScript plugin which would create these effects for you if you don't mind taking that route (see curvy corners for example).

Css rounded corners with border

I use css to apply rounded corners to li navigation elements. This elements have a border too.
So this is how it looks like:
Like you can see the quality of the rounded corner - border combination is strange, there is a bit of white shining through.
Any idea how to fix that? Do I have to use bg-images?
Unfortunately, yes, you should use background images. Some browsers don't properly handle actual borders with border-radius. You can even see this happening to Stack Overflow's badge styles (which also use border-radius) on Firefox. I don't think you can do anything to fix the border-radius issue other than to report bugs to the respective vendors.
Yes it can be done using this jquery plugin.
http://jquery.malsup.com/corner/
No corner images, uses nested divs to draw borders. It's flexible and easy to use. It also has Added support for native border-radius so it only executes on browsers that do not support supports border-radius.

IE9 problems with css such gradient background and rounded corners and shadow

I use a gradient background color for selected or hovered menu items it works fine in chrome,FF,opera,ie7,ie8 . but in ie9 the background of the elements appears in the right of the element but text keeps in place this is the first problem.
the second problem i faced is the rounded corner it works fine in chrome, FF, opera but in ie9 the corners are ok but the background of the box was an image but it appears white!!!
the third problem is that of shadow
i apply shadow to the divs containing images it works fine in all browsers but ie9 offset the whole div instead of applying shadow and opacity change on mouse over increased the problem by adding black parts in the side of div that doesn't have shadow???????
when i heard that ie9 supports css3 i knew that this is unbelievable ie will still be my Nightmare!!
I'm afraid of future appearance of the website in ie 9 so i add this
<meta http-equiv="X-UA-Compatible" content="IE=7.5"/>
when i used IE=7 or IE=8 the problem still as it is
but know it appears better after adding that line but with no support for rounded corner.
How are you telling IE9 to implement the corners and gradients? Are you using the IE filters (like I assume you're using for 7 and 8)? Or are you actually using CSS3?
If you're using filters, try making IE9 just use CSS3. You can put the filters into their own stylesheet and just use conditional comments to target IE8 and below for them, so IE9 ignores the filters altogether, that way you know they're not interfering.

possible to have a background color transition from color A to color B without repeating a pixel stick?

For things like menubars and headers, a background color is nice.
But a background color that gracefully transitions from say Blue to White is even nicer.
I know this can be done by making a 1-pixel wide, X-pixel tall image file containing the desired fade and repeating it across the div, but does CSS have native support to just define colors and be done with it?
Can any other language handle this?
With CSS3, you can do that. However, CSS3 is not widely supported through browsers, so only the most recent of browsers (and not even all of them) will be able to display the gradient. Unless you're only interested in working with those browsers that can do it, you're going to have to stick with the 1px background image.

You mean a gradient?
Webkit browsers(Chrome and Safari), and apparently FF 3.6 now support CSS gradients:
see this link
According to the article, even IE has some proprietory CSS gradient support, I don't know how well that works though. You should always have a fallback to solid color though.
