Is it possible to make a box arrow in css 3 with a gradient

If you look at the link below, you will see a floating green box with the arrow pointing left:

Can this be done using only CSS3? Is it possible to make the arrow shape and have a gradient that is both in the box and the arrow? If so, how 开发者_JS百科would you do this?

Thanks

Tested in IE9 and recent versions of Firefox, Chrome, Safari, Opera.

HTML:

<span class="tooltip">Hover me</span>

CSS:

.tooltip {
    position: relative;
    display: inline-block;
    font: 13px sans-serif;
    height: 60px;
    line-height: 60px;
    border: 1px solid #444
}
.tooltip:hover:before {
    content: 'Add new authorisation';

    top: 50%;

This was the closest I could get with pure css and HTML... the only problem is the arrow tip which can't use the gradient.

<div class="arrow"></div><div class="content">Add new authorization</div>

.arrow
{
    width:2px;
    height:2px;
    border: 12px inset black;
    border-right-width: 8px;
    border-color: transparent #5a0 transparent transparent;
}
.content
{
    background-color: green;
    padding:2px 8px 2px 4px;
    border: 1px solid #490;
    border-left-width: 0px;
    background-image: -webkit-linear-gradient(top, #8c0, #070);
    text-shadow: 1px 1px #8c0, -1px -1px #070
}
div {float:left; color:white;
}
