请看一下http://jsfiddle.net/ghAgQ/我需要箭头的相同渐变,就像矩形一样。任何想法如何做到这一点?谢谢

.rectangle {
background-color: #EEE;
height: 80px;
width: 240px;
border: 1px solid #CCC;
background: white;
cursor: pointer;
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,white),             color-stop(37%,#F1F1F1), color-stop(57%,#E1E1E1), color-stop(100%,#F6F6F6));
float: left;
}

.arrow {

border-top: 41px solid transparent;
border-bottom: 41px solid transparent;

You can do this in a much simpler way, using just an element and a rotated pseudo element (any browser that supports CSS gradients also supports CSS transforms and pseudo-elements) with an angled linear gradient. Also, don't use the old WebKit syntax (see this bit about the history of the syntax).

您可以以更简单的方式执行此操作,只使用一个元素和一个旋转的伪元素(任何支持CSS渐变的浏览器也支持CSS变换和伪元素)和一个带角度的线性渐变。另外,不要使用旧的WebKit语法(请参阅此位有关语法的历史记录)。

Working in current versions of Chrome, Opera, Firefox, IE on Windows.

DEMO

HTML is just <div class='rectangle'></div>

HTML只是

Relevant CSS:

.rectangle {
    float: left;
    position: relative;
    height: 80px;
    width: 240px;
    border: solid 1px #ccc;
    border-right: none;
    background: #eee linear-gradient(white, #f1f1f1 37%, #e1e1e1 57%, #f6f6f6);
    cursor: pointer;
}
.rectangle:after {
    position: absolute;
    top: 16px; right: -25px;
    width: 48px;
    height: 47px;
    border-left: solid 1px #ccc;
    border-top: solid 1px #ccc;
    transform: rotate(134deg) skewX(-10deg) skewY(-10deg);
    background: #eee linear-gradient(45deg, white, #f1f1f1 37%, #e1e1e1 57%, #f6f6f6);
    content: '';
}

Edit January 2013

4 months later, I have a slightly improved solution. This time, the values are computed. The first time I got them using trial and error.

4个月后,我的解决方案略有改进。这次,计算值。我第一次使用反复试验得到它们。

new demo

.shape {
    float: left;
    position: relative;
    border: 1px solid #ccc;
    border-right: none;
    width: 240px; height: 80px;
    background: linear-gradient(white, #f1f1f1 37%, #e1e1e1 57%, #f6f6f6);
    cursor: pointer;
}
.shape:after {
    position: absolute;
    top: 50%; right: 0;
    margin: -24px -20px;
    border-top: solid 1px #ccc;
    border-right: solid 1px #ccc;
    width: 40px /* 80px/2 */; height: 47px/* 80px/sqrt(3) */;
    transform: rotate(30deg) skewY(30deg); /* create a rhombus */
    /* 49.1deg = atan(1.15) = atan(47px/40px) */
    background: 
            linear-gradient(-49.1deg, #f6f6f6, #e1e1e1 43%, #f1f1f1 63%, white);
    content: ''
}

<div class='shape'></div>

While the demo above looks really nice in Chrome, any browser support information is missing and it does not work in many browsers. I have spend some time to develop a more cross-browser approach.

虽然上面的演示在Chrome中看起来非常不错,但是缺少任何浏览器支持信息,并且它在许多浏览器中都不起作用。我花了一些时间来开发更多的跨浏览器方法。
