Pointed/angled arrow-style borders in CSS

Question

I\'m making a breadcrumb menu and attempting to do it in pure CSS so I don\'t have to use a background image to get an arrow shape. Is it possible to achieve this angled border

Answer 1

you can get those borders too if you want (I have improved the previous answer by Olaf Dietsche):

HTML:

    

        
Hurr
        
Durr
        
Furr
    

CSS:

li.breadcrumb:before {
    content:'';
    width: 28.28427px; /* sqrt(40*40 / 2) */
    height: 28.28427px;
    background:transparent;
    position:absolute;
    -moz-transform:rotate(45deg);
    -webkit-transform:rotate(45deg);
    transform:rotate(45deg);
    transform-origin: top right;
    top: 20px;
    margin:0;
    right: 0;
    border-right: #000 solid 1px;
    border-top: #000 solid 1px;
}

li.breadcrumb:after {
    content: "";
    display: inline-block;
    width: 0;
    height: 0;
    border-top: 20px solid #eee;
    border-bottom: 20px solid #eee;
    border-left: 20px solid #ccc;
}
li.first-crumb:after {
    border-top: 20px solid #ccc;
    border-bottom: 20px solid #ccc;
    border-left: 20px solid #aaa;
}
li.last-crumb:after {
    border-top: 20px solid #fff;
    border-bottom: 20px solid #fff;
    border-left: 20px solid #eee;
}

li.breadcrumb {
    list-style-type: none;
    background-color: #ccc;
    display: inline-block;
    float: left;
    line-height: 0;
    position: relative;
    height: 40px;
}
li.first-crumb {
    background: #aaa;
}
li.last-crumb {
    background: #eee;
}
li.breadcrumb a {
    text-decoration: none;
}
