你犯了一些HTML和CSS格式错误。修复下面的代码。你描述的一个问题是ul元素的风格定义引起的——为了解决你的问题，你需要在那里应用z-ndex。

$("#slideshow > div:gt(0)").hide();
setInterval(function() {
  $('#slideshow > div:first')
    .fadeOut(1000)
    .next()
    .fadeIn(1000)
    .end()
    .appendTo('#slideshow');
}, 3000);
.menu_div{background-color: #333; width:100%;}
ul {
    list-style-type: none;
    margin: 0 auto;
    display:table;
    padding: 0;
    z-index: 100;
    overflow: hidden;
}
li {
    float: left;
}
li a, .dropbtn {
    display: inline-block;
    color: white;
    text-align: center;
    padding: 14px 16px;
    text-decoration: none;
}

    background-color: black;

   z-index: 100;

设法修复它添加z-index:1000;css，干杯kevin

.menu_div { 
  position: relative;
  z-index: 0;
  border: dashed;
  height: 2.9em;
  margin-bottom: 0em;
  margin-top: 0em;
  z-index:1000
