如何在 <nav id="top"> opencart v2.3 中制作波浪形/锯齿形边框

Question

我正在尝试在<nav id="top"> opencart v2.3 中获得波浪形/锯齿形边框。而不是平坦的边框。

something like this

下面是css代码

 #top {
    background-color: #EEEEEE;
    border-bottom: 1px solid #e2e2e2;
    padding: 4px 0px 3px 0;
    margin: 0 0 20px 0;
    min-height: 40px;
}
