I have a list, and each item is linked, is there a way I can alternate the background colors for each item?
How about some lovely CSS3?
li { background: green; }
li:nth-child(odd) { background: red; }
Try adding a pair of class attributes, say 'even' and 'odd', to alternating list elements, e.g.
<ul>
<li class="even"><a href="link">Link 1</a></li>
<li class="odd"><a href="link">Link 2</a></li>
<li class="even"><a href="link">Link 3</a></li>
<li class="odd"><a href="link">Link 4</a></li>
<li class="even"><a href="link">Link 5</a></li>
</ul>
In a <style> section of the HTML page, or in a linked stylesheet, you would define those same classes, specifying your desired background colours:
li.even { background-color: red; }
li.odd { background-color: blue; }
You might want to use a template library as your needs evolve to provide you with greater flexibility and to cut down on the typing. Why type all those list elements by hand?
You can achieve this by adding alternating style classes to each list item
<ul>
<li class="odd"><a href="link">Link 1</a></li>
<li><a href="link">Link 2</a></li>
<li class="odd"><a href="link">Link 2</a></li>
<li><a href="link">Link 2</a></li>
</ul>
And then styling it like
li { backgorund:white; }
li.odd { background:silver; }
You can further automate this process with javascript (jQuery example below)
$(document).ready(function() {
$('table tbody tr:odd').addClass('odd');
});
