html - how to make this gradient vertical

Question

I have a horizontal gradient bar: example

I am wondering, how to make it vertical instead of horizontal, with about 20px height.

HTML:

<div class="seperator-gradient"></div>

CSS:

.seperator-gradient {
    width: 100%;
    height: 10px;
    border-bottom: background: #c4c4c4;
    background: -moz-linear-gradient(left, #ffffff 0%, #e3e3e3 10%, #b8b8b8 50%, #e3e3e3 90%, #fcfcfc 100%);
    background: -webkit-gradient(linear, left top, right top, color-stop(0%,#ffffff), color-stop(10%,#e3e3e3), color-stop(50%,#b8b8b8), color-stop(90%,#e3e3e3), color-stop(100%,#fcfcfc));
    background: -webkit-linear-gradient(left, #ffffff 0%,#e3e3e3 10%,#b8b8b8 50%,#e3e3e3 90%,#fcfcfc 100%);
    background: -o-linear-gradient(left, #ffffff 0%,#e3e3e3 10%,#b8b8b8 50%,#e3e3e3 90%,#fcfcfc 100%);
    background: -ms-linear-gradient(left, #ffffff 0%,#e3e3e3 10%,#b8b8b8 50%,#e3e3e3 90%,#fcfcfc 100%);
    background: linear-gradient(to right, #ffffff 0%,#e3e3e3 10%,#b8b8b8 50%,#e3e3e3 90%,#fcfcfc 100%);
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffffff', endColorstr='#fcfcfc',GradientType=1 ); 


}

Try this:

.seperator-gradient {
    width: 100%;
    height: 10px;
    border-bottom: background: #c4c4c4;
    background: -moz-linear-gradient(left, #ffffff 0%, #e3e3e3 10%, #b8b8b8 50%, #e3e3e3 90%, #fcfcfc 100%);
    background: -webkit-gradient(linear, left top, right top, color-stop(0%,#ffffff), color-stop(10%,#e3e3e3), color-stop(50%,#b8b8b8), color-stop(90%,#e3e3e3), color-stop(100%,#fcfcfc));
    background: -webkit-linear-gradient(left, #ffffff 0%,#e3e3e3 10%,#b8b8b8 50%,#e3e3e3 90%,#fcfcfc 100%);
    background: -o-linear-gradient(left, #ffffff 0%,#e3e3e3 10%,#b8b8b8 50%,#e3e3e3 90%,#fcfcfc 100%);
    background: -ms-linear-gradient(left, #ffffff 0%,#e3e3e3 10%,#b8b8b8 50%,#e3e3e3 90%,#fcfcfc 100%);
    background: linear-gradient(to right, #ffffff 0%,#e3e3e3 10%,#b8b8b8 50%,#e3e3e3 90%,#fcfcfc 100%);
    filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffffff', endColorstr='#fcfcfc',GradientType=1 ); 
    transform: rotate(90deg);
    -ms-transform: rotate(90deg); 
    -webkit-transform: rotate(90deg);

}

This will rotate what you have 90 degrees. I'm next to positive it's in the right direction, but if this goes the opposite way, change (90deg) to (270deg).
