Here is simplified variation of @kougiland's.

div {
    width:200px;
    height:60px;
    position:relative;
    text-indent:30px;
    line-height:60px;
}
div:before{
    content: '';
    position: absolute;
    top: 14px;
    left: 0px;
    width: 17px;
    border-bottom: 1px solid blue;
    border-left: 1px solid blue;
    -webkit-transform: skew(0deg,60deg);
    -moz-transform: skew(0deg,60deg);
    transform: skew(0deg,60deg);
}
div:after{
    content: '';
    position: absolute;
    left: 0px;
    bottom: 14px;
    width: 17px;
    border-top: 1px solid blue;
    border-left: 1px solid blue;
    -webkit-transform: skew(0deg,-60deg);
    -moz-transform: skew(0deg,-60deg);
    transform: skew(0deg,-60deg);
}

Answer 3

Using the technique of creating triangles with transparent borders of divs. Two attempts that might help you a bit,

HTML

<div class="button">
    <div class="wrapper">
        <div class=" top-side "></div>
        <div class="arrow-right "></div>
        <div class="arrow-right2 "></div>
        <div class="bottom-side "></div>
    </div>
</div>

CSS

.button {
    width: 400px;
    background-color:orange;
}
.wrapper{
    background-color:blue;
    width:2px;
}
.arrow-right {
    width: 0;
    height: 0;
    border-top: 5px solid transparent;
    border-bottom: 5px solid transparent;
    border-left: 15px solid white;
    position:absolute;
    z-index:2;
}
.arrow-right2 {
    position:relative;
    top:-1px;
    z-index:1;
    width: 0;
    height: 0;
    border-top: 6px solid transparent;
    border-bottom: 6px solid transparent;
    border-left: 18px solid blue;
}
.top-side {
    height:7px;
    width:2px;
    background-color:blue;
}
.bottom-side {
    height:7px;
    width:2px;
    background-color:blue;
}

You might get better result by tweaking them.

Answer 4

The background is not solid which makes it very hard. Especially since your arrow is not 90 degrees, which won't render that smooth I guess. But have a look at this question:
