如何创建一个如下所示的菜单:
我不想使用PSD图像.我更喜欢使用像FontAwesome这样的包中的图标，并在CSS中生成背景/CSS.
可以找到使用PSD来生成工具提示的图像然后使用它的菜单的版本here.
推荐答案
Almost 3 years later, I finally made the time to revisit this and post an improved version. You can still view the original answer at the end for reference.
While SVG may be the better choice, especially today, my goal with this was to keep it just HTML and CSS, no JS, no SVG, no images (other than the background on the root element).

HTML非常简单.我正在使用复选框黑客来显示/隐藏菜单.
<input type='checkbox' id='t'/>
<label for='t'>✰</label>
<ul>
<li><a href='#'>☀</a></li>
<li><a href='#'>☃</a></li>
<li><a href='#'>☁</a></li>
</ul>
我使用Sass来保持这一逻辑，并在需要时使更改变得更容易. comments 很多.
