CSS3 breadcrumbs

A breadcrumb navigation allow users to know where they are in a hierarchical structure and navigate back to higher-level pages in the hierarchy. Also, the breadcrumbs can reduce the number of actions a user need to perform in order to navigate back.

So, to keep it simple, if you have a website with lot of pages and sub-levels, in order to increase usability, you need to use breadcrumbs. Having said that, today you’ll learn how to create your own cool CSS3 breadcrumbs.

The HTML

Tha markup is simple and minimal, based on an unordered list.

<ul id="breadcrumbs-one">
    <li><a href="">Lorem ipsum</a></li>
    <li><a href="">Vivamus nisi eros</a></li>
    <li><a href="">Nulla sed lorem risus</a></li>
    <li><a href="">Nam iaculis commodo</a></li>
    <li><a href="" class="current">Current crumb</a></li>
</ul>

The CSS

First, let’s add a mini CSS reset for our unordered lists:

ul{
  margin: 0;
  padding: 0;
  list-style: none;
}

Secondly, I’d like to add that all the breadcrumbs I made for this tutorial are using CSS pseudo-elements. I bet there’s no need to specify what pseudo-elements are and how cool they are.

First example

Here I used a similar technique to the one I used for creating these CSS3 tooltips. Basically, to create a right-bordered triangle effect, the triangles created with pseudo-elements are placed one above another. The darker triangle will be shifted a bit in order to achieve the border.

#breadcrumbs-one{
  background: #eee;
  border-width: 1px;
  border-style: solid;
  border-color: #f5f5f5 #e5e5e5 #ccc;
  border-radius: 5px;
  box-shadow: 0 0 2px rgba(0,0,0,.2);
  overflow: hidden;
  width: 100%;
}

#breadcrumbs-one li{
  float: left;
}

#breadcrumbs-one a{
  padding: .7em 1em .7em 2em;
  float: left;
  text-decoration: none;
  color: #444;
  position: relative;
  text-shadow: 0 1px 0 rgba(255,255,255,.5);
  background-color: #ddd;
  background-image: linear-gradient(to right, #f5f5f5, #ddd);
}

#breadcrumbs-one li:first-child a{
  padding-left: 1em;
  border-radius: 5px 0 0 5px;
}

#breadcrumbs-one a:hover{
  background: #fff;
}

#breadcrumbs-one a::after,
#breadcrumbs-one a::before{
  content: "";
  position: absolute;
  top: 50%;
  margin-top: -1.5em;
  border-top: 1.5em solid transparent;
  border-bottom: 1.5em solid transparent;
  border-left: 1em solid;
  right: -1em;
}

#breadcrumbs-one a::after{
  z-index: 2;
  border-left-color: #ddd;
}

#breadcrumbs-one a::before{
  border-left-color: #ccc;
  right: -1.1em;
  z-index: 1;
}

#breadcrumbs-one a:hover::after{
  border-left-color: #fff;
}

#breadcrumbs-one .current,
#breadcrumbs-one .current:hover{
  font-weight: bold;
  background: none;
}

#breadcrumbs-one .current::after,
#breadcrumbs-one .current::before{
  content: normal;
}

Second example

The CSS shapes built with the pseudo-elements are placed before, respectively after.

#breadcrumbs-two{
  overflow: hidden;
  width: 100%;
}

#breadcrumbs-two li{
  float: left;
  margin: 0 .5em 0 1em;
}

#breadcrumbs-two a{
  background: #ddd;
  padding: .7em 1em;
  float: left;
  text-decoration: none;
  color: #444;
  text-shadow: 0 1px 0 rgba(255,255,255,.5);
  position: relative;
}

#breadcrumbs-two a:hover{
  background: #99db76;
}

#breadcrumbs-two a::before{
  content: "";
  position: absolute;
  top: 50%;
  margin-top: -1.5em;
  border-width: 1.5em 0 1.5em 1em;
  border-style: solid;
  border-color: #ddd #ddd #ddd transparent;
  left: -1em;
}

#breadcrumbs-two a:hover::before{
  border-color: #99db76 #99db76 #99db76 transparent;
}

#breadcrumbs-two a::after{
  content: "";
  position: absolute;
  top: 50%;
  margin-top: -1.5em;
  border-top: 1.5em solid transparent;
  border-bottom: 1.5em solid transparent;
  border-left: 1em solid #ddd;
  right: -1em;
}

#breadcrumbs-two a:hover::after{
  border-left-color: #99db76;
}

#breadcrumbs-two .current,
#breadcrumbs-two .current:hover{
  font-weight: bold;
  background: none;
}

#breadcrumbs-two .current::after,
#breadcrumbs-two .current::before{
  content: normal;
}

Third example

Using border-radius we will round the corners for our rectangle and square shapes. The square will be rotated, in order to achieve a rounded diamond.

#breadcrumbs-three{
  overflow: hidden;
  width: 100%;
}

#breadcrumbs-three li{
  float: left;
  margin: 0 2em 0 0;
}

#breadcrumbs-three a{
  padding: .7em 1em .7em 2em;
  float: left;
  text-decoration: none;
  color: #444;
  background: #ddd;
  position: relative;
  z-index: 1;
  text-shadow: 0 1px 0 rgba(255,255,255,.5);
  border-radius: .4em 0 0 .4em;
}

#breadcrumbs-three a:hover{
  background: #abe0ef;
}

#breadcrumbs-three a::after{
  background: #ddd;
  content: "";
  height: 2.5em;
  margin-top: -1.25em;
  position: absolute;
  right: -1em;
  top: 50%;
  width: 2.5em;
  z-index: -1;
  transform: rotate(45deg);
  border-radius: .4em;
}

#breadcrumbs-three a:hover::after{
  background: #abe0ef;
}

#breadcrumbs-three .current,
#breadcrumbs-three .current:hover{
  font-weight: bold;
  background: none;
}

#breadcrumbs-three .current::after{
  content: normal;
}

Fourth example

Again, with the pseudo-elements you’ll add two rectangles before and after the element. Then you’ll round the outer sides for each one. The rest is nothing but poetry. :)

#breadcrumbs-four{
  overflow: hidden;
  width: 100%;
}

#breadcrumbs-four li{
  float: left;
  margin: 0 .5em 0 1em;
}

#breadcrumbs-four a{
  background: #ddd;
  padding: .7em 1em;
  float: left;
  text-decoration: none;
  color: #444;
  text-shadow: 0 1px 0 rgba(255,255,255,.5);
  position: relative;
}

#breadcrumbs-four a:hover{
  background: #efc9ab;
}

#breadcrumbs-four a::before,
#breadcrumbs-four a::after{
  content:'';
  position:absolute;
  top: 0;
  bottom: 0;
  width: 1em;
  background: #ddd;
  transform: skew(-10deg);
}

#breadcrumbs-four a::before{

  left: -.5em;
  border-radius: 5px 0 0 5px;
}

#breadcrumbs-four a:hover::before{
  background: #efc9ab;
}

#breadcrumbs-four a::after{
  right: -.5em;
  border-radius: 0 5px 5px 0;
}

#breadcrumbs-four a:hover::after{
  background: #efc9ab;
}

#breadcrumbs-four .current,
#breadcrumbs-four .current:hover{
  font-weight: bold;
  background: none;
}

#breadcrumbs-four .current::after,
#breadcrumbs-four .current::before{
  content: normal;
}
