CSS Vertical Navigation with Teaser

CSS Vertical Navigation with Teaser

Tags: Beginner
This technique is a simple way to display some teaser information for your vertical navigation. I won’t waste any of your time with an intro, let’s get right into the code.

HTML

We will start by creating a list item, but in this case, we will add an empty ‘span’ tag inside of the hyper link. The CSS will look at the content of the span tag as a display: none until it’s hovered over.

<ul class="sidenav">
 <li>
  <a href="#">Home
  <span>Blandit turpis patria euismod at iaceo appellatio, demoveo esse. Tation utrum utrum abigo demoveo immitto aliquam sino aliquip. </span>
  </a>
 </li>
 <li>
  <a href="#">Blog
  <span>Blandit turpis patria euismod at iaceo appellatio, demoveo esse. Tation utrum utrum abigo demoveo immitto aliquam sino aliquip. </span>
  </a>
 </li>
 <li>
  <a href="#">Tutorials
  <span>Blandit turpis patria euismod at iaceo appellatio, demoveo esse. Tation utrum utrum abigo demoveo immitto aliquam sino aliquip. </span>
  </a>
 </li>
</ul>

CSS

We will first style the vertical navigation list. What I like to do is add a light bevel look on each of the navigation links.

ul.sidenav {
 font-size: 1.2em;
 float: left;
 width: 200px;
 margin: 0;
 padding: 0;
 list-style: none;
 background: #005094;
 border-bottom: 1px solid #3373a9;
 border-top: 1px solid #003867;
}
ul.sidenav li a{
 display: block;
 color: #fff;
 text-decoration: none;
 width: 155px;
 padding: 10px 10px 10px 35px;
 background: url(sidenav_a.gif) no-repeat 5px 7px;
 border-top: 1px solid #3373a9;
 border-bottom: 1px solid #003867;
}

Then we will now add the hide/show effect when it’s hovered.

ul.sidenav li a:hover {
 background: #003867 url(sidenav_a.gif) no-repeat 5px 7px;
 border-top: 1px solid #1a4c76;
}
ul.sidenav li span{ display: none; }
ul.sidenav li a:hover span {
 display: block;
 font-size: 0.8em;
 padding: 10px 0;
}

Bevel Colors

How did I choose the right colors to achieve the bevel look?

1. Open Photoshop
2. Create a new document of any size, I just did a random size of 300×300
3. Fill the background with your <ul> base background color.
4. Using your marquee tool, set it to the ‘single row marquee tool’
5. Create a new layer and fill it with white
6. Duplicate this layer but this time fill it with black.
7. Now lower the opacity on those layers: Black Layer: 30% / White Layer 20%
8. Now using the Eyedropper tool, select the two colors.

Conclusion

In addition to adding teaser information to the navigation, this technique can be modified to add descriptions to any element of page. You could add teaser descriptions to profile names, question-and-answer type FAQ pages, navigation, or a multitude of other applications.
