How to apply -webkit-gradient to IE?

问题:

I have the following css code:

-webkit-gradient(linear, left bottom, left top, from(#5AE), to(#036));

Which displays the background very nicely in Chrome. Internet explorer just displays a white background. I tried applying CSS 3 pie, which didnt change anything.

Following is my css:

body {
  behavior: url(css3pie/PIE.htc);
    color: #000000;
    font-family: Arial, Helvetica, sans-serif;
    margin: 0px;
    padding: 0px;
    /*background:url("../image/bg.png") repeat scroll 0 0 transparent;*/
    background: -webkit-gradient(linear, left bottom, left top, from(#5AE), to(#036)); 
}

Thanks

-webkit-gradient() is for webkit browsers only (Safari, Chrome, etc). This means it will not work in Firefox, Internet Explorer, Opera, or any other browser that does not support -webkit-gradient().

If you want to get gradient in all modern browsers, try the following code:

/* Firefox 3.6+ */

/* Chrome 7+ & Safari 5.03+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0, rgba(0,51,102,1)), color-stop(1, rgba(85,170,238,1)));

/* Newer Browsers */
background: linear-gradient(top, rgba(0,51,102,1), rgba(85,170,238,1));

/* IE5.5 - IE7 */
filter: progid:DXImageTransform.Microsoft.Gradient(GradientType=0,StartColorStr=#FF003366,EndColorStr=#FF55AAEE);

/* IE8 */
-ms-filter: "progid:DXImageTransform.Microsoft.Gradient(GradientType=0,StartColorStr=#FF003366,EndColorStr=#FF55AAEE)"

Note: You don't need any external JavaScript library to get gradients in IE. Simply use the CSS from above ;) However, for your own sanity, I would suggest using a preprocessor such as LESS or SASS so you can have all of the browser-specific versions automatically generated.

The CSS3 PIE documentation has this example for linear gradients:

#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);
}

You are missing the -pie-background property.

As an aside, you should use the "new webkit" syntax instead of the one you currently have; it's been quite a while since Webkit abandoned it.

For IE8 you can add this

background: #aaa;
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#111111', endColorstr='#aaaaaa',GradientType=1);

For IE9 the following will work

background-image: -ms-linear-gradient(left, #111, #aaa);
