This question already has an answer here:
I am trying to get CSS3PIE to work for my site so I can use border-radius in IE8 (and earlier). It works fine in all other browsers. Here's my CSS:
#body_text_design{
    border:2px solid black;
    background-color:#CCC;
    background-image:url(../pics/designbg.png);
    font-family:"Britannic Bold";
    color:black;
    height:676px;
    width:675px;
    -webkit-border-radius:10px;
    -moz-border-radius: 10px;
    border-radius: 10px;
    margin-top:23px;
    overflow:hidden;
    behavior: url(PIE.htc);
    }
And my HTML:
<div id="body_box">
    <div id="body_text_design">
    <div class="design_text_div">
    <h1>Test test test</h1>
    <br />
    <br />
    <br />
    <h3>Bla bla bla</h3> 
    <h3>Test test test</h3>
    </div>
    </div>
</div>
I have tried all the debugging that I could find such as:
- tried the PHP solution
- tried a full http:// link to the PIE.htc file
- added AddType text/x-component .htcto my .htaccess file
- tried position:absoluteandzoom:1and z-index values.
Nothing has worked so far. I envy those that have gotten this just by adding the behavior property to their CSS. If anybody could help, that would be greatly appreciated!
EDIT
Here's a jsfiddle:
Make sure you are not testing locally. .htc files needs to be hosted on server and css3 pie will work only in web container
I was struggling with this problem for awhile and finally figured it out!
Some servers don't recognize the .htc file so you have to add the Content-type to your .htaccess file by putting this:
AddType text/x-component .htc
It's on the known issues page of the documentation http://css3pie.com/documentation/known-issues/
I have access to the .htaccess but it made no difference adding AddType text/x-component .htc, however using the PIE.php did work (although I had been using a mistyped path at first so took me 3 days to work out that the php really did work all along!)... anyway, all looking good now!
