Does not work border-radius IE8

Question

To implement the border-radius in IE8 I use border-radius.htc

The block in which to work correctly realzovat border-radius:

.mc-button
{
    -moz-transition: all 0.218s ease 0s;
    -moz-user-select: none;
    background-color: #CBCBCB;
    background-image: -moz-linear-gradient(center top , #CBCBCB, #DCDCDC);
    border: 1px solid #DCDCDC;
    color: #FFFFFF;
    cursor: default;
    display: inline-block;
    font-size: 11px;
    font-weight: bold;
    height: 29px;
    line-height: 29px;
    min-width: 70px;
    padding: 0 8px !important;
    text-align: center;
    overflow: visible;
    font-family: inherit;
    font-size: inherit;
    float: left;
    text-decoration: none;
    display: block;
    -webkit-border-radius: 5px;
    -khtml-border-radius: 5px;
    -moz-outline-radius: 5px;
    -moz-border-radius: 5px;
    border-radius: 5px;
    font-family: Arial, Sans-Serif !important;
    behavior:url(Content/border-radius.htc);
}

According to the list of attached files - border-radius.htc connects to the page

Can you please tell how to solve the problem?

UPDATE (06/13/2012)

If the code is replaced by a button:

.mc-button
{
    border: 1px solid #696;
    height: 29px;
    line-height: 29px;
    min-width: 70px;
    text-align: center;
    padding: 0 8px !important;
    overflow: visible;
    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    border-radius: 5px;
    float: left;
    display: block;
    background: #00ADEE;
    background: -webkit-gradient(linear, 0 0, 0 bottom, from(#00ADEE), to(#0078A5));
    background: -webkit-linear-gradient(#00ADEE, #0078A5);
    background: -moz-linear-gradient(#00ADEE, #0078A5);
    background: -ms-linear-gradient(#00ADEE, #0078A5);
    background: -o-linear-gradient(#00ADEE, #0078A5);
    background: linear-gradient(#00ADEE, #0078A5);
    -pie-background: linear-gradient(#00ADEE, #0078A5);
    behavior: url("Content/PIE.htc");
}

and to declare as:

<a id="login_button" class="mc-button mc-button-submit ">SomeText</a>

.mc-button-submit
{
    border: 0px solid #0076A3;
    background: #00ADEE;
    background: -webkit-gradient(linear, 0 0, 0 bottom, from(#00ADEE), to(#0078A5));
    background: -webkit-linear-gradient(#00ADEE, #0078A5);
    background: -moz-linear-gradient(#00ADEE, #0078A5);
    background: -ms-linear-gradient(#00ADEE, #0078A5);
    background: -o-linear-gradient(#00ADEE, #0078A5);
    background: linear-gradient(#00ADEE, #0078A5);
    -pie-background: linear-gradient(#00ADEE, #0078A5);
    color: #FFFFFF;
    text-align: center;
}

Rounding it disappears. Adding to the .mc-button-submit line behavior: url ("Content / PIE.htc"); does not help.

Can you please tell how to connect a second class with the parameters of the background?

Answer 1

Standalone .htc hack is not working for background gradient and border-radius both at the same time.

Try to replace css gradient with simple image. This trick will work.

Also you can use css3pie (thanks to @dop-trois) — this pure Javascript tool is more perfect than standalone .htc file.

PS. Inset box-shadow s cannot be implemented in both solutions.

PPS: the code you need is here: (i changed it a bit to make it more valid and correct):

.mc-button {
    font: bold 11px/29px Arial, Helvetica, sans-serif !important;
    text-align: center;
    text-decoration: none;
    color: #FFFFFF;

    border: 1px solid #DCDCDC;
    height: 29px;
    min-width: 70px;
    padding: 0 8px !important;
    overflow: visible;
    display: block;

    float: left;

    /* Unique link for this gradient — http://www.colorzilla.com/gradient-editor/#cbcbcb+0,dcdcdc+100;Custom */
    background-color: #CBCBCB;
    background: -moz-linear-gradient(top,  rgba(203,203,203,1) 0%, rgba(220,220,220,1) 100%); /* FF3.6+ */
    background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(203,203,203,1)), color-stop(100%,rgba(220,220,220,1))); /* Chrome,Safari4+ */
    background: -webkit-linear-gradient(top,  rgba(203,203,203,1) 0%,rgba(220,220,220,1) 100%); /* Chrome10+,Safari5.1+ */
    background: -o-linear-gradient(top,  rgba(203,203,203,1) 0%,rgba(220,220,220,1) 100%); /* Opera 11.10+ */
    background: -ms-linear-gradient(top,  rgba(203,203,203,1) 0%,rgba(220,220,220,1) 100%); /* IE10+ */
    background: linear-gradient(top,  rgba(203,203,203,1) 0%,rgba(220,220,220,1) 100%); /* W3C */

    /* css3 stuff below: (via css3please.com) */
    /* no one prefix except `-webkit` is needed nowadays for `border-radius` */
    -webkit-border-radius: 5px;
            border-radius: 5px;
    -webkit-transition: all 0.218s ease-out;
       -moz-transition: all 0.218s ease-out;
        -ms-transition: all 0.218s ease-out;
         -o-transition: all 0.218s ease-out;
            transition: all 0.218s ease-out;

    /* PIE specific accordingly http://css3pie.com/documentation/q-and-a/ */
    behavior: url(PIE.htc);
}

You should be sure that you have included PIE.htc correctly (important!)

Relative questions

• Using CSS3Pie htc for border-radius in IE8
• CSS3 PIE - Giving IE border-radius support not working?
• CSS3 PIE - Giving IE border-radius support not working?

Accordingly to answers possible problems may be in mime type ("text/x-component").

Also possible solution may be:

position: relative;
z-index: 0;

Answer 2

To apply gradients and border-radius, I recommend CSS3 Pie . It's the most powerful tool i know, to apply CSS3 properties in IEs.

Apply gradients in IEs):

#myElement {
    background: #CCC; /*fallback for non-CSS3 browsers*/
    background: -webkit-gradient(linear, 0 0, 0 100%, from(#CCC) to(#EEE)); /*old webkit*/
    background: -webkit-linear-gradient(#CCC, #EEE); /*new webkit*/
    background: -moz-linear-gradient(#CCC, #EEE); /*gecko*/
    background: -ms-linear-gradient(#CCC, #EEE); /*IE10*/
    background: -o-linear-gradient(#CCC, #EEE); /*opera 11.10+*/
    background: linear-gradient(#CCC, #EEE); /*future CSS3 browsers*/
    -pie-background: linear-gradient(#CCC, #EEE); /*PIE*/
    behavior: url(PIE.htc);
}​

Apply border-radius in IEs):

#myAwesomeElement {
    border: 1px solid #999;
    -webkit-border-radius: 10px;
    -moz-border-radius: 10px;
    border-radius: 10px;
    behavior: url(path/to/PIE.htc);
}​

You'll need PHP to get it work.

Live demo on CSS3 Pie's website.

Btw.: Applying border-radius & gradients the same time is possible with this tool ;)

Hope this helps :)

Answer 3

To apply Gradients, Box shadows and Border-radius, I recommend CSS3 Pie. I used it in cook&smile project and it fully works in IE.

*{ behavior:url(path/PIE.htc);}

.border_radius_div{ position:relative; -webkit-border-radius: 10px; -moz-border-radius: 10px;  border-radius: 10px;}

.gradient_div{ position:relative; 
background: #EEFF99;
background: -webkit-gradient(linear, 0 0, 0 bottom, from(#EEFF99), to(#66EE33));
background: -webkit-linear-gradient(#EEFF99, #66EE33);
background: -moz-linear-gradient(#EEFF99, #66EE33);
background: -ms-linear-gradient(#EEFF99, #66EE33);
background: -o-linear-gradient(#EEFF99, #66EE33);
background: linear-gradient(#EEFF99, #66EE33);
-pie-background: linear-gradient(#EEFF99, #66EE33); }

Note:

1. Don't forget to use position (relative or absolute) where we are using Border-radius, gradients and box shadows.

2. Don't forget to use behavior:url(xhtml_folder/PIE.htc);

3. And the important thing is don't forget to put the PIE.htc in xhtml folder.
