javascript - CSS 水平导航菜单列表对齐

标签 javascript jquery html css

我正在尝试设计一个菜单和子菜单，例如 this .

我尝试对已有的菜单进行增强，但它并不是从菜单的开头开始。我尝试编辑 CSS，但不知道在哪里解决此问题。

这是我尝试修复的菜单的屏幕截图。

enter image description here

菜单的 HTML:

<div style="width:100%; border:1px solid black" align="center">
<ul id="nav-one" class="dropmenu" style="width:1024px; border:1px solid black;">

如何解决这个问题？

最佳答案

修复您拥有的这两个类:

.dropmenu li{
    list-style: none;
    float: left;
    margin: 0px;
    padding: 0px;
}

还有这个

.products{
    left:0;
    width: 1024px;
    padding: 0px !important;
}

直接替换即可
