Question

我正在使用导航栏下拉菜单，他在尝试定位宽度为100％的下拉菜单时遇到了一些麻烦，但是每当我将宽度设置为100％时，它会扩展到右边而不是左边。

这里是我工作项目预览的链接。希望有人可以帮助解决小问题。

Answer 1

你需要为＆＃39; left＆＃39;添加一个值。像这样的nav-content div：

   .nav-content {
        position: absolute;
        top: 13.3em;
        z-index: -1;
        padding: 1.3em 0 !important;
        overflow: hidden;
        width: 100%;
        background-color: #a656dc;
        left: 0; /*add this*/
    }

并将菜单中心添加margin：auto到ul元素，如下所示：

    .nav-content ul {
        margin:auto;
    }
