重叠<li elements - CSS海关

我已经遇到了悬停导航栏及其标签下拉菜单选项的css编码 . 我博客博客的链接如下：http://www.blankesque.com .

我在悬停导航栏中有三个选项卡/页面，当鼠标/光标悬停在相关文本上时会显示下拉菜单选项 . 然而，我遇到的问题是，当光标或鼠标悬停在其中一个标签/页面文本上时 - 在这种情况下，它们的 Headers 为“Blankesque”，“社交”和“功能” - 下拉菜单选项与标签重叠/页面 Headers . 理想情况下，我希望下拉菜单选项显示在相关 Headers 下方，而不是重叠并覆盖它们 .

我在下面包含了html和css编码 .
