Question

I have this css code which is only supported in Firefox.

/* Green header */
.container {
    background: linear-gradient(#5FA309, #3B8018);
    position: relative;
    display: inline-block;
    padding: 0 20px 0 10px;
    width: 270px;
    line-height: 20px;
    font-size: 12px;
    font-family: sans-serif;
    text-shadow: 0 1px 0 #264400;
    font-weight: bold;
    color: #fff;
}

.container:after {
    content: '';
    background: linear-gradient(top left, #5FA309, #3B8018);
    background: -webkit-gradient(linear, left top, left bottom, from(#5FA309), to(#3B8018));
    background: -moz-linear-gradient(top left,  #5FA309,  #3B8018);
    position: absolute;
    top: 3px; right: -7px;
    width: 15px;
    height: 15px;
    transform: rotate(45deg);
}

How I can make this code also supported on IE? I want to use only css without images.

Note the use of the -ms- vendor prefix and the order in which vendor prefixes are set:

.container{
    background:-webkit-gradient(linear, left top, left bottom, color-stop(0, #5fa309), color-stop(1, #3b8018));
    background:-webkit-linear-gradient(top, #5fa309 0%, #3b8018 100%);
    background:-moz-linear-gradient(top, #5fa309 0%, #3b8018 100%);
    background:-o-linear-gradient(top, #5fa309 0%, #3b8018 100%);
    background:-ms-linear-gradient(top, #5fa309 0%, #3b8018 100%);
    background:linear-gradient(top, #5fa309 0%, #3b8018 100%);
    position:relative;
    display:inline-block;
    padding:0 20px 0 10px;
    width:270px;
    line-height:20px;
    font-size:12px;
    font-family:sans-serif;
    text-shadow:0 1px 0 #264400;
    font-weight:bold;
    color:#fff
}
.container:after{
    content:'';
    background:-webkit-gradient(linear, left top, right bottom, color-stop(0, #5fa309), color-stop(1, #3b8018));
    background:-webkit-linear-gradient(top left, #5fa309 0%, #3b8018 100%);
    background:-moz-linear-gradient(top left, #5fa309 0%, #3b8018 100%);
    background:-o-linear-gradient(top left, #5fa309 0%, #3b8018 100%);
    background:-ms-linear-gradient(top left, #5fa309 0%, #3b8018 100%);
    background:linear-gradient(top left, #5fa309 0%, #3b8018 100%);
    position:absolute;
    top:3px;
    right:-7px;
    width:15px;
    height:15px;
    -webkit-transform:rotate(45deg);
    -moz-transform:rotate(45deg);
    -o-transform:rotate(45deg);
    -ms-transform:rotate(45deg);
    transform:rotate(45deg)
}
