今天有空把前几天学的东西发一下，都是一些简单的东西，但是千里之行始于足下，我虽然走的慢，但是未停下前进的脚步,
下来看下我做的“淡入的文字”最终动态效果：
上面这个动画效果制作的过程是：
（1）先自定义一个透明度从0到1变化的动画，然后在animation中调用这个动画效果
（2）注意不同行文字出现的时间先后，这个通过animation中延时属性可以实现
（3）规定文字最终动态为动画的最终显示状态，否则文字显示完会自动消失，这个用animation-fill-mode可以实现
一、先来看看HTML中程序：
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>淡入的文字</title> <link type="text/css" rel="stylesheet" href="css/animate.css" /> </head> <body> <div class="fade-in-words"> <div class="first-words">山一程，水一程，</div> <div class="second-words">身向榆关那畔行，</div> <div class="third-words">夜深千帐灯。</div> <div class="four-words">风一更，雪一更，</div> <div class="five-words">聒碎乡心梦不成，</div> <div class="six-words">故园无此声。</div> </div> </body> </html>
上面这段程序主要是先把文字呈现出来，我随便找了一首诗啦~~~~~大家不要去猜它的意思QAQ
二、看看CSS样式（主要是CSS3）

200px;

上面的程序我在注释里面都写得很清楚，感兴趣的可以看我写的注释，我觉得比较简单，没有难度，但是需要注意浏览器前缀的添加，否则你懂得.
