This is a quick CSS tutorial to show you how to create a menu
list using either the CSS border style or a background image. The trick
is to apply a bottom border to the <li>
element, then
use the absolute position property to shift the nested elements down to
cover the border. It is very flexible — you can easily change the
layout by altering the border or background image. It even works when
the browser's font size is being scaled (increased or decreased).
1. HTML Code
Take a look at the HTML code and the diagram. They will help you understand how the CSS work.
<ul>
<li><strong>CSS Design</strong> <em>250<sup>95</sup></em></li>
</ul>
2. CSS Code
The key points are:
- Specify the
<li>
element toposition:relative
and apply a bottom border style. - Use
position:absolute
with negativebottom
value to shift the<strong>
and<em>
element below the border. - Remember: use relative value (em) to control the padding space.
.menu {
width: 500px;
list-style: none;
margin: 0 0 2em;
padding: 0;
font: 150%/100% Arial, Helvetica, sans-serif;
}
.menu li {
clear: both;
margin: 0;
padding: 0 0 1.8em 0;
position: relative;
border-bottom: dotted 2px #999;
}
.menu strong {
background: #fff;
padding: 0 10px 0 0;
font-weight: normal;
position: absolute;
bottom: -.3em;
left: 0;
}
.menu em {
background: #fff;
padding: 0 0 0 5px;
font: 110%/100% Georgia, "Times New Roman", Times, serif;
position: absolute;
bottom: -.2em;
right: 0;
}
.menu sup {
font-size: 60%;
color: #666;
margin-left: 3px;
}
3. Change Border Style
You can easily change the style by editing the CSS border
and padding
for the <li>
element.
li {
border-bottom: dashed 1px #000;
padding: 0 0 2.3em 0;
}
4. Use Image as Border (see final demos)
You can also use a background image.
li {
background: url(images/circle.gif) repeat-x left bottom;
}
5. IE6 Version (see IE6 demo)
If you are still using the old and buggie IE6 browser, you may notice
the layout doesn't render properly. To fix the issue, simply add the clearfix trick to the <li>
element.
/* clearfix */
.menu li:after {
content: ".";
display: block;
height: 0;
clear: both;
visibility: hidden;
}
.menu li {display: inline-block;}
/* Hides from IE-mac \*/
* html .menu li {height: 1%;}
.menu li {display: block;}
/* End hide from IE-mac */
