将鼠标悬停在背景文字上时，下拉菜单消失

标签： css

我无法利用我正在开发的网站上的主下拉菜单，因为如果移动速度太慢或将鼠标悬停在其后面的子元素中背景中的文本上，它将消失。

我尝试添加！important标签。我试图寻找元素之间的任何空白。我尝试调整z轴优先级值。 

.dropdown {
        position: fixed;
        top: 1vmin;
        left: 1vmin;
        width: 10vmin;

                        <a href="#">Link 2</a>
                        <a href="#">Link 3</a>
                </div>
        </div>
        <div class="header" style="background-color:black;">
<table style="background-color:black;">
        <tr>
        <td><a href="#">Home</a></td>
        <td><a href="#">IT</a></td>
        <td><a href="#">Science</a></td>
        <td><a href="#">Tech</a></td>
        <td><a href="#">News</a></td>
        <td><a href="#">Top</a></td>
        </tr>
        </table>
        </div>
        <div class="mainbody">
        <h1>RoyHQ</h1>
        </div>
</body>
</html>

我希望下拉菜单可以相对消失。不是，几乎无法使用。
