为什么右键菜单插件的contextmenu的保存和退出的div一开始没有显示在页面中，CSS也没看到display:none，求赐教？？？

<div class="title"><span class="fl">点击右键</span></div>
<div class="content">
<input id="btnSubmit" type="button" value="提交" />
<div class="tip"></div>
</div>
<div class="contextMenu" id="sysMenu">
<ul>
<li id="Li3"><img src="http://img1.sycdn.imooc.com//52e4b34b0001bb6d00160016.jpg" alt="" />保存</li>
<li id="Li4"><img src="http://img1.sycdn.imooc.com//52e4b3680001424900160016.jpg" alt="" />退出</li>
</ul>
</div>
</div>
<script type="text/javascript">
$(function () {
$("#divtest").contextMenu('sysMenu',
{ bindings:
{
'Li3': function (Item) {
$(".tip").show().html("您点击了“保存”项");
},
'Li4': function (Item) {
$(".tip").show().html("您点击了“退出”项");
}
}
});
});
</script>
</body>
</html>
加粗部分没有显示出来
下面是CSS
#divtest
{
width: 282px;
}
#divtest .title
{
padding: 8px;
background-color: Blue;
color: #fff;
height: 23px;
line-height: 23px;
font-size: 15px;
font-weight: bold;
}
#divtest .content
{
padding: 8px 0px;
background-color: #fff;
font-size: 13px;
}
#divtest .content .tip
{
text-align: center;
border: solid 1px #ccc;
background-color: #eee;
margin: 20px 0px;
padding: 8px;
display: none;
}
.fl

}
