CSS3实现的闪烁跳跃进度条示例(附源码)
(编辑:jimmy 日期: 2024/11/17 浏览:3 次 )
这个示例的原理是通过大量的css3属性来实现的,如:animation、transform、keyframes等等属性。值得注意的是这个示例采用了结构性伪类选择符E:nth-child(n),来进行对HTML元素的选择以及控制输出。相信这个伪类选择符在将来会是一个很强大的一个工具。推荐大家多多了解以及实践使用。这个伪类选择符E:nth-child(n)的含义是匹配父元素的第n个子元素E。 例如:ul li:nth-child(3)表示的是选择<ul>元素里面的第3个<li>。提示一下,该属性在IE8(包含IE8)版本以下是不支持的。
