css - 没有图像的三 Angular 形式面包屑

Question

我使用 CSS 创建了箭头(三 Angular 形)样式的面包屑，没有图像。

jsFiddle

html:

<ul class="breadcrumb">
    <li>Home</li>
    <li>First item</li>
    <li>Second item</li>
    <li>Last item</li>
</ul>

CSS:

.breadcrumb {
    list-style: none;
    overflow: hidden;
}
.breadcrumb li {
    background: #F6F6F6;
    padding: 5px 0 5px 36px;
    background: #F6F6F6;
    position: relative;
    display: block;
    float: left;
}
.breadcrumb li:before {
    content:" ";
    display: block;
    width: 0;
    height: 0;
    border-top: 25px solid transparent;
    border-bottom: 25px solid transparent;
    border-left: 20px solid #DDDDDD;
    position: absolute;
    top: 50%;
    margin-top: -25px;
    margin-left: 1px;
    left: 100%;
    z-index: 1;
}
.breadcrumb li:after {
    content:" ";
    display: block;
    width: 0;
    height: 0;
    border-top: 25px solid transparent;
    border-bottom: 25px solid transparent;
    border-left: 20px solid #F6F6F6;
    position: absolute;
    top: 50%;
    margin-top: -25px;
    left: 100%;
    z-index: 2;
}

问题是当父级的宽度不足以在 1 行中显示面包屑并且需要 2 行(或更多)时，overflow:hidden 停止工作并且不需要的三 Angular 形部分变得可见(http://screencloud.net/v/fQEq)。

有办法解决吗？

试试这种风格:

.breadcrumb {
    list-style: none;
    overflow: hidden;
}
.breadcrumb li:before {
    border-bottom: 15px solid transparent;
    border-left: 20px solid #dddddd;
    border-top: 15px solid transparent;
    content:" ";
    display: block;
    height: 0;
    left: 100%;
    margin-left: 1px;
    margin-top: -15px;
    position: absolute;
    top: 50%;
    width: 0;
    z-index: 1;
}
.breadcrumb li:after {
    border-bottom: 15px solid transparent;
    border-left: 20px solid #f6f6f6;
    border-top: 15px solid transparent;
    content:" ";
    display: block;
    height: 0;
    left: 100%;
    margin-top: -15px;
    position: absolute;
    top: 50%;
    width: 0;
    z-index: 2;
}
.breadcrumb li {
    background: none repeat scroll 0 0 #f6f6f6;
    display: block;
    float: left;
    height: 20px;
    padding: 5px 0 5px 33px;
    position: relative;
}
