$(document).ready(function() {

        in milliseconds ( multiplied with 1000) '*/

                of infinity by changing place of last or first item*/

html代码

<div id='carousel_container'>
<div id='left_scroll'><a href='网页特效:slide("left");'><img src='left.png' /></a></div>
    <div id='carousel_inner'>
        <ul id='carousel_ul'>
            <li><a href='#'><img src='item1.png' /></a></li>
            <li><a href='#'><img src='item2.png' /></a></li>
            <li><a href='#'><img src='item3.png' /></a></li>
            <li><a href='#'><img src='item4.png' /></a></li>
            <li><a href='#'><img src='item5.png' /></a></li>

        </ul>
    </div>
<div id='right_scroll'><a href='javascript:slide("right");'><img src='right.png' /></a></div>
<input type='hidden' id='hidden_auto_slide_seconds' value=0 />
</div>

我觉得只有一个这些属性需要进一步解释。我们的无序列表的左边距为- 210px。这是因为最后一个项目，将在第一项动议，所以我们设置左边距到该项目的宽度负数。

css代码

#carousel_inner {
float:left; /* important for inline positioning */
width:630px; /* important (this width = width of list item(including margin) * items shown */
overflow: hidden; /* important (hide the items outside the div) */
/* non-important styling bellow */
background: #f0f0f0;
}

#carousel_ul {
position:relative;
left:-210px; /* important (this should be negative number of list items width(including margin) */
list-style-type: none; /* removing the default styling for unordered list items */
margin: 0px;
padding: 0px;
width:9999px; /* important */
/* non-important styling bellow */
padding-bottom:10px;
}

#carousel_ul li{
float: left; /* important for inline positioning of the list items */
width:200px; /* fixed width, important */
/* just styling bellow*/
padding:0px;
height:110px;
background: #000000;
margin-top:10px;
margin-bottom:10px;
margin-left:5px;
margin-right:5px;
}

#carousel_ul li img {
.margin-bottom:-4px; /* ie is 易做图 a 4px gap bellow an image inside of an anchor (<a href...>) so this is to fix that */
/* styling */
cursor:pointer;
cursor: hand;
border:0px;
}
#left_scroll, #right_scroll{
float:left;
height:130px;
width:15px;
background: #c0c0c0;
}
#left_scroll img, #right_scroll img{
border:0; /* remove the default border of linked image */
/*styling*/
cursor: pointer;
cursor: hand;

}
