是否可以创建适用于桌面和触摸屏浏览器的漂亮的多级菜单？没有任何js。由于触摸屏没有:hover属性，为两种变体创建一个样式表让我抓狂。在桌面上的行为应该是：悬停 - 打开子菜单，点击 - 转到链接。在 iPad 上：第一次点击 - 打开子菜单，第二次点击 - 转到链接。
感谢您的任何建议。

使用纯 CSS，目标:hoverAND:active来完成你想要的。
在您的 iPhone/iPad 上试用此网站：www.thepricklepatch.com。它并不完美，但这就是我正在做的事情来创造我想要的效果。
编辑： 对不起，我花了这么长时间才回复 - 这个周末正在露营，不允许使用电脑！:) 这是该站点的 CSS，被剥离以获得您想要的位。我已经为你添加了评论。这里有一些我用来样式化菜单的空规则，并且我删除了任何处理纯外观并专注于元素定位的 CSS。
/* NAVIGATION ************************************************************************/
nav > ul > li
{
display: inline-block; /* sets elems to be inline but retain block-like properties, you may not need this */
position: relative; /* resets the positioning context */
cursor: pointer; /* sets the mouse cursor to look like a link for menus that do not have an A element */
}
nav > ul > li:hover
{
position: relative; /* reset positioning context */
z-index: 2000; /* bring element top-most */
}
nav > ul > li:hover,
nav > ul > li:hover > a /* HOVERED list elems and links in the main menu */
{
}
nav > ul > li,
nav > ul > li > a /* list elems and links in the menu */
{
}
nav > ul > li > div.submenu /* only first level of submenus */
{
display: none; /* hide the submenus by default */
}
nav > ul > li:hover > div.submenu /* Only HOVERED OVER first level of submenus */
{
display: block; /* display the submenus when the LI is hovered over */
position: absolute;
top: 100%; /* set to the bottom of the menu */
left: -1px; /* move left 1px from left of LI element */
z-index: 1000; /* top most */
}
nav > ul div.submenu /* All submenus */
{
}
nav > ul div.submenu > ul /* All lists of links in a submenu */
{
background: #fff;
padding: 2px;
border: solid 2px #f89d57;
}
nav > ul div.submenu > ul > li, /* All list elements in any submenu */
nav > ul div.submenu > ul > li > a /* All list elements containing links in any submenu */
{
}
nav > ul div.submenu > ul > li
{
}
nav > ul div.submenu > ul > li > a
{
display: block;
}
nav > ul div.submenu > ul > li,
nav > ul div.submenu > ul > li > a /* All links in any submenu */
{
}
nav > ul div.submenu > ul > li:hover /* All HOVERED li containing links in any submenu */
{
}
nav > ul div.submenu > ul > li:hover > a /* All links HOVERED in any submenu */
{
}
nav div.submenu > ul > li > div.submenu,
nav div.submenu > ul > li > a + div.submenu /* 2nd level of submenus and on */
{
display: none; /* Hide by default submenus */
}
nav div.submenu > ul > li:hover div.submenu,
nav div.submenu > ul > li:hover a + div.submenu /* 2nd level submenus and on (if even used) */
{
display: block; /* Show submenus when parent hovered */
position: absolute;
top: -2px;
left: 75%;
z-index: 1000;
}
nav li:hover
{
position: relative;
z-index: 2000;
}

如果您的主菜单节点没有链接到任何地方，您可以使用 JavaScript 轻松完成此操作。您可以将其添加为可在触摸设备上使用的点击功能。
您也可以使用 :focus 和 :active 状态与兄弟选择器结合使用。这将允许菜单与键盘导航一起显示，这是一个优点，但您必须添加一些 JavaScript 以使其在您切换到子菜单链接时不会隐藏。
<ul>
<li>
<a class="menuLink" href="javascript:void(0);">Menu 1</a>
<ul class="submenu">
<li><a href="page">Submenu Link</a></li>
<li><a href="page">Submenu Link</a></li>
<li><a href="page">Submenu Link</a></li>
<li><a href="page">Submenu Link</a></li>
</ul>
</li>
<li>
<a class="menuLink" href="javascript:void(0);">Menu 2</a>
<ul class="submenu">
<li><a href="page">Submenu Link</a></li>
<li><a href="page">Submenu Link</a></li>
<li><a href="page">Submenu Link</a></li>
<li><a href="page">Submenu Link</a></li>
</ul>
</li>
<li>
<a class="menuLink" href="javascript:void(0);">Menu 3</a>
<ul class="submenu">
<li><a href="page">Submenu Link</a></li>
<li><a href="page">Submenu Link</a></li>
<li><a href="page">Submenu Link</a></li>
<li><a href="page">Submenu Link</a></li>
</ul>
</li>
<li>
<a class="menuLink" href="javascript:void(0);">Menu 4</a>
<ul class="submenu">
<li><a href="page">Submenu Link</a></li>
<li><a href="page">Submenu Link</a></li>
<li><a href="page">Submenu Link</a></li>
<li><a href="page">Submenu Link</a></li>
</ul>
</li>
<ul>
使用这样的 CSS：
.submenu { display:none; }
.menuLink:hover + .submenu,
.menuLink:focus + .submenu,
.menuLink:active + .submenu {
display:block;
}
