OK, cool.
First up you need to close your unordered list;
Code:
<div id="slider">
<ul>
<li><a href="http://templatica.com/preview/30"><img src="images/01.jpg" alt="Css Template Preview" /></a></li> </ul>
Then you need to link to the correct javascript files in your head tags (obviously making sure the are pointed to the right place);
Code:
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/easySlider1.5.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#slider").easySlider();
});
</script>
The link references above show the javascript files sat in a folder called 'js' in the root of your website. Which is how I generally arrange javascript files for sites.
Then copy the CSS styles;
Code:
/* Easy Slider */
#slider ul, #slider li{
margin:0;
padding:0;
list-style:none;
}
#slider li{
/*
define width and height of list item (slide)
entire slider area will adjust according to the parameters provided here
*/
width:696px;
height:241px;
overflow:hidden;
}
span#prevBtn{}
span#nextBtn{}
/* // Easy Slider */
Into your stylesheet and alter to suit.
Come back when you've done all that and let me know if it is working.
