create an arrow using css

Question

Is there any way to create an arrow like that in the following button, using CSS?

I know how to create triangle-like arrows like this

#triangle_arrow {
        top: 3pt;
        content: "";
        display: inline-block;
        width: 0.5em;
        height: 0.5em;
        border-right: 0.1em solid black;
        border-top: 0.1em solid black;
        transform: rotate(45deg);
    }

but that line towards the arrow's corner is confusing me!

Answer 1

Already there is way through which you could achieve this i.e. suggested by James, but you could even do this using pseudo selectors or using pre-defined icons using font awesome to get an arrow icon next to some tag, as below.

Solution 1:

#box{
  width:100px;
  height:50px;
  background:blue;
  position:relative;
}    
#box:before{
        top: 20px;
        right:10px;
        content: "";
        display: inline-block;
        width: 0.5em;
        height: 0.5em;
        border-right: 0.1em solid white;
        border-top: 0.1em solid white;
        transform: rotate(45deg);
        position:absolute;
}
#box > p:after{
  content:'';
  width:20px;
  height:1px;
  background:white;
  right:10px;
  top:24px;
  position:absolute;
}
#box > p{
  font-size:24px;
  color:#fff;
  padding:10px;
  box-sizing:border-box;
}

<div id="box">
<p>Next</p>
</div>

Solution 2 :

#box{
  width:100px;
  height:50px;
  background:blue;
  position:relative;
}    
#box > p{
  font-size:24px;
  color:#fff;
  padding:10px;
  box-sizing:border-box;
}
#box > p > .fa{
  color:#fff;
  font-size:16px;
}

<div id="box">
<p>Next <i class="fa fa-arrow-right"></i></p>
</div>
