CSS后面还有一个点是什么意思

CSS后面还有一个点是什么意思,第1张

就是嵌套的关系咯, 看你上面的css,

应该是这样调用:

<div class="qV_boxCon ">

<ul class="lpic">

<li>xxx</li>

</ul>

</div>

要用JS来控制的，单纯的CSS做不到，给你个代码，可以直接拿去用：

<div id="dpro" style="overflow:hiddenwidth:100%px padding:10px margin:0 10px">

                    <table width="100%" border="0" cellspacing="0" cellpadding="0">

                      <tr>

                        <td id="dpro1">

                        <table width="100%" cellpadding="0" cellspacing="0" border="0">

                            <tr>

                    

<td><div class="index_pic"><a href="product_show.asp?id=41" title="轻轮"><img src="UploadFiles/20131017164757151.png" width="148" height="139" /><span>轻轮</span></a></div></td>

只有css根本看不出来是哪里出错了，我这里有一个比较不错的你可以考虑下换个试试：
