Nav溢出框阴影

Question

nav标签溢出了CSS中的框阴影，因此显示边框。我已经尝试了从增加可见性的所有事情：一直到在nav标签上使用z-index属性，但是它们都不起作用。该网站为http://www.lvowebdesign.nl。我知道CSS不干净并且有很多错误，但是在我让我发疯之前，我需要一个眼睛新鲜的人。有很多“！important”，因为bulm css会覆盖css。 nav标签发生了什么？这个可以解决吗？

这是HTML代码：

    <nav>

          </a>
        </li>

这是CSS代码：

nav ul {

您也可以在导航中添加box-shadow属性，但这只是一个快速修复。我真的建议您更好地组织代码，并可以将box-shadow添加到主div。

nav {
  padding: 0px 0 0px !important;
  height: 60px !important;
  background: white !important;
  box-shadow:
      inset 10px 0px 10px -10px rgba(0, 0, 0, 0.5),
      inset -10px 0px 10px -10px rgba(0, 0, 0, 0.5);
}
