html - 横向菜单 : how to float right but keep the menu items in the correct order?

Question

我对水平菜单 (.drop_menu li) 使用 float: right，因为我希望菜单与屏幕右侧对齐( Logo 与左侧对齐)。它工作正常，唯一的问题是我的菜单项现在的顺序错误(链接 3 然后链接 3 然后链接 1 而不是相反)。有没有办法解决这个问题？非常感谢

Answer 1

从 li 中删除 float:right 以防止顺序颠倒。

将 float:right 添加到 ul 的 .dropdown 类，将整个菜单放在右侧。

将 float:left 添加到 li 以帮助您的子菜单保持对齐。

.drop_menu {
    float: right;  
}
.drop_menu li { 
    display: table-cell;
    vertical-align: middle;
    float:left;
}
