jquery - 固定菜单在 WOW slider 下

Question

我的 WOW slider 出现问题，向下滚动时菜单位于其下方而不是上方。

我该怎么做才能解决这个问题？我似乎尝试将 z-index: 100 甚至 99999 应用于菜单/导航栏，但它仍然在它下面。

<div class="navigation stick">
        <div id="menu">
            <div class="nav">
                <li><a href="#frontpage">Frontpage</a></li>
                <li><a href="#aboutme">About Me</a></li>
                <li><a href="#experience">Experience</a></li>
                <li><a href="#projects">Projects</a></li>
                <li><a href="#contact">Contact Me</a></li>
            </div>
        </div>
    </div>


<div id="textcontainer">
                <div id="textbox">
                    Here is a overview of my current and previous projects. Click on the picture to get more information.
                </div>
                <div id="slider_container">
                    <div id="wowslider-container1">
                        <div class="ws_images">
                            <ul>
                                <li><img src="img/projects/c17_big.jpg" title="City 17"/>A roleplay gamemode for testing.</li>
                                <li><img src="img/projects/heartbit_big.jpg" title="HeartBit Roleplay"/>HeartBit Roleplay</li>
                                <li><img src="img/projects/tb_big.jpg" title="TigerBit"/>TigerBit</li>
                            </ul>
                        </div>

                        <div class="ws_bullets">
                            <div>
                            <a href="#">1</a>
                            <a href="#">2</a>
                            <a href="#">3</a>
                            </div>
                        </div>
                    </div>
                </div>
                <script type="text/javascript" src="slider_engine/wowslider.js"></script>
                <script type="text/javascript" src="slider_engine/script.js"></script>

            </div>

以及代码的 CSS:

.nav{
    height: 60px;
    width: 100%;
    padding-top: 20px;


    font-family: "Open Sans Condensed";
    font-weight: bold;
    font-size: 2em;
    text-transform: uppercase;

    display: table;
    text-align: center;
    margin: auto;
}

.nav li{
    display: table-cell;
    width: 1420px;
    float: none;
}

.nav li a{
    color: white;
}

.nav li a:hover{
    height: 30px;
    background-color: transparent;
    color: orange;
}

#slider_container{
    margin-bottom: 100px;
    z-index: 1;
}

Answer 1

所以你试试:

.navigation{
  position: relative;
  z-index: 10;
}
#textcontainer {
  position: relative;
  z-index: 1;
}

如果你的元素在线，我可以看看是什么问题，如果你方便的话，可以把代码放到codepen .io中吗？
