Introduction to CSS Part4

In this lesson we covered the concept of using breadcrumbs as a secondary navigation method for a site:

  • Use breadcrumbs to indicate where a user is and the extent of the site
  • Breadcrumbs are implemented using unordered lists in HTML with custom CSS styling
  • Three types of breadcrumbs exist:
  • location - based on hierarchical structure of site
  • attribute - based on attributes of current page or item
  • path - unique to a user’s journey on the site
  • Path-based breadcrumbs can be confusing, only use if needed
  • Ensure breadcrumbs will add value before adding to a site

Example:

.breadcrumb li{
  display: inline;
}

.breadcrumb li.location+li.location::before{
  padding:10px;
  color:blue;
  content: ">"
}

.breadcrumb a:hover{
  text-decoration: underline;
}

.breadcrumb li.attribute a {
  color: gray;
}
.breadcrumb li.attribute::after {
  content: "x";
  color: red;
  font-size: 10px;
  vertical-align: super;
}

making arrows of breadcrumbs:

.breadcrumb {
  text-align: left;
}
// ................................. making the body of the arrow:

.breadcrumb li {
  float: left;
}


.breadcrumb a {
  color: #fff;
  background: darkcyan;
  text-decoration: none;
  position: relative;
  height: 30px;
  line-height: 30px;
  text-align: center;
  margin-right: 15px;
  padding: 0 5px;
}

// ...................................... making it an arrow:

.breadcrumb a::before,
.breadcrumb a::after {
  content: "";
  position: absolute;
  border-color: darkcyan;
  border-style: solid;
  border-width: 15px 5px;
}
.breadcrumb a::before {
  left: -10px;
  border-left-color: transparent;
}
.breadcrumb a::after {
  left: 100%;
}
.breadcrumb a::after {
  left: 100%;
  border-color: transparent;
  border-left-color: darkcyan;
}

// ................................. styling

.breadcrumb a:hover {
  background-color: blue;
}
.breadcrumb a:hover::before {
  border-color: blue;
  border-left-color: transparent;
}
.breadcrumb a:hover::after {
  border-left-color: blue;
}
