Breadcrump with css - html

Question

In this fiddle I create a simple breadcrumb. I like to change the dependencies of class "div.arrow-right". I like to control the arrow size by "#sequence". So that the size of the arrow belongs to the font-size. That means if I change the font-size the right-arrow should fit automatically the same high as the div which contains the writing.
#sequence {
font-size: 28px;
}
And I like to add a gap or lets say a white thin arrow between two breadcrumb elements, see the picture below.

Answer 1

An alternate using :before and :after pseudo elements. Fiddle
.breadcrumb {
list-style: none;
overflow: hidden;
font-size: 28px;
}
.breadcrumb li {
color: white;
text-decoration: none;
padding: 8px 0 8px 50px;
position: relative;
display: block;
float: left;
cursor: pointer;
}
.breadcrumb li:after {
content: "";
display: block;
width: 0;
height: 0;
border-top: 50px solid transparent;
border-bottom: 50px solid transparent;
border-left: 30px solid #74c476;
position: absolute;
top: 50%;
margin-top: -50px;
left: 100%;
z-index: 2;
}
.breadcrumb li:before {
content: " ";
display: block;
width: 0;
height: 0;
border-top: 50px solid transparent;
border-bottom: 50px solid transparent;
border-left: 30px solid white;
position: absolute;
top: 50%;
margin-top: -50px;
margin-left: 2px;
left: 100%;
z-index: 1;
}
li:nth-child(1) {
padding-left: 20px;
background-color: #74c476;
}
li:nth-child(2) {
background-color: #61a362;
}
li:nth-child(3) {
background-color: #518851;
}
li:nth-child(1):after {
border-left-color: #74c476;
}
li:nth-child(2):after {
border-left-color: #61a362;
}
li:nth-child(3):after {
border-left-color: #518851;
}
<ul class="breadcrumb">
<li>hello</li>
<li>operator</li>
<li>layout</li>
</ul>
