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!">
" P/ z) H- Z2 t l7 M - Label for your tooltip
7 ?" i8 P: i) {; l - </span>
复制代码CSS代码: - .tooltip-toggle {* Z0 C" a) i; b. s! C( ]/ ^
