Tooltips 对于展示一些信息非常有用,并且不需要什么用户体验。目前有很多 JavaScript 插件实现了这个功能,但是如果你不想使网站更加的笨重,那我们可以使用普通的 CSS 来实现它. 我们可以使用伪元素来拉取信息,并在 :hover 时显示它(你可以使用 HTML 的 title 属性来实现完成的解决方案,但是不能自定义喜欢的样式). HTML代码: - <span class="tooltip-toggle" data-tooltip="Sample text for your tooltip!">
Z" W$ H$ Z. r! r - Label for your tooltip* V6 Q+ @0 Q4 Y
- </span>
复制代码CSS代码: - .tooltip-toggle {) }0 Q; }+ q( ^2 l2 [0 h$ {) d& Z

复制代码下拉菜单 如果你想实现一个简单的下拉菜单,你可以通过 CSS 的 :hover 简单的触发菜单的隐藏. HTML代码: - <div class="nav-container">% ]* q3 u3 i0 a: K, _/ m
