纯CSS垂直菜单与子菜单 [英] pure css vertical menu with submenu

问题描述

我做了我的研究，能够复制我正在寻找的东西，我只需要帮助更具体的垂直，纯CSS，菜单。

I did my research and was able to replicate what I'm looking for, well kind of--I just need help with a more specific vertical, pure CSS, menu.

我想让我的子菜单弹出窗口在a的左边显示10px而不是 li 属性，就像在互联网上找到的大多数示例一样。我也在寻找最简单，纯粹的CSS，菜单类型 - 没有什么奇特。

I want my sub-menu popup to appear 10px to the left of the a not the li attribute like most example found on the internet. I'm also looking for the most simple, pure CSS, type of menu--Nothing fancy.

这是我到目前为止做的：

Here's what I've done so far:

<div id="nav">
    <ul class="top-level">
        <li><a href="#">This is a long text</a>
            <ul class="sub-level">
                <li><a href="#">Sub Menu Item 1</a></li>
                <li><a href="#">Sub Menu Item 2</a></li>
                <li><a href="#">Sub Menu Item 3</a></li>
                <li><a href="#">Sub Menu Item 3</a></li>
            </ul>
        </li>
        <li><a href="#">About</a></li>
        <li><a href="#">Contact me here</a></li>
        <li><a href="#">Help</a>
            <ul class="sub-level">
                <li><a href="#">Sub Menu Item 1</a></li>
                <li><a href="#">Sub Menu Item 2</a></li>
                <li><a href="#">Sub Menu Item 3</a></li>
            </ul>
        </li>
    </ul>

my css：

#nav {border:1px solid cyan;}
    /* top level menu */
    #nav ul.top-level {border:1px solid red;}
    #nav ul.top-level li {position:relative;}

    /* sub level menu */
    #nav ul.sub-level {border:1px solid yellow;}
    #nav ul.sub-level {display:none;} /* hide */

    /* hover the sub menu*/
    #nav ul.top-level li:hover .sub-level {display: block; position:absolute; top:5px;}

如何使它这样子菜单弹出时， a HTML锚点而不是 li ，并且点击的 / code> anchor？
谢谢。

How do I make it so the sub level menu pops up when I hover the a HTML anchor, not the li, and 10px to the left of the clicked a anchor? Thanks.
