今天有空把前几天学的东西发一下，都是一些简单的东西，可是千里之行始于足下，我虽然走的慢，可是未停下前进的脚步,css

下来看下我作的“淡入的文字”最终动态效果：html

上面这个动画效果制做的过程是：web

（1）先自定义一个透明度从0到1变化的动画，而后在animation中调用这个动画效果浏览器

（2）注意不一样行文字出现的时间前后，这个经过animation中延时属性能够实现动画

（3）规定文字最终动态为动画的最终显示状态，不然文字显示完会自动消失，这个用animation-fill-mode能够实现spa

1、先来看看HTML中程序：code

<!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">夜深千账灯。</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~~~~~你们不要去猜它的意思QAQhtm

2、看看CSS样式（主要是CSS3）blog

.fade-in-words{
    width: 200px;
    margin: 0 auto;
    text-align: center;
}

/*自定义一个透明度从0到1的动画，它的名称是fade-in*/
@keyframes fade-in{  
    0%{ opacity: 0;}
    100%{opacity:1;}
}
@-webkit-keyframes fade-in{
    0%{ opacity: 0;}
    100%{opacity:1;}
}
@-ms-keyframes fade-in{
    0%{ opacity: 0;}
    100%{opacity:1;}
}
@-o-keyframes fade-in{
    0%{ opacity: 0;}
    100%{opacity:1;}
}
@-moz-keyframes fade-in{
    0%{ opacity: 0;}
    100%{opacity:1;}
}
.first-words{ 
    opacity: 0;      /*实先规定文字的状态是不显示的*/
    animation: fade-in 4s ease 0s 1;    /*调用名称为fade-in的动画，全程动画显示时间4S，进入方式为ease，延时0S进入，播放次数1次*/
    -webkit-animation: fade-in 4s ease 0s 1;
    -moz-animation: fade-in 4s ease 0s 1;
    -o-animation: fade-in 4s ease 0s 1;
    -ms-animation: fade-in 4s ease 0s 1;
    
    /*规定动画的最后状态为结束状态*/

    -o-animation: fade-in 4s ease 4s 1;
    -ms-animation: fade-in 4s ease 4s 1;
    
    /*规定动画的最后状态为结束状态*/
    animation-fill-mode:forwards;
    -webkit-animation-fill-mode: forwards;  
      -o-animation-fill-mode: forwards; 
      -ms-animation-fill-mode: forwards;

    -o-animation: fade-in 4s ease 6s 1;
    -ms-animation: fade-in 4s ease 6s 1;
    
    /*规定动画的最后状态为结束状态*/
    animation-fill-mode:forwards;
    -webkit-animation-fill-mode: forwards;  
      -o-animation-fill-mode: forwards; 
      -ms-animation-fill-mode: forwards;   
      -moz-animation-fill-mode: forwards; 
}
.five-words{ 
    opacity: 0;    
    animation: fade-in 4s ease 8s 1;
    -webkit-animation: fade-in 4s ease 8s 1;
    -moz-animation: fade-in 4s ease 8s 1;
    -o-animation: fade-in 4s ease 8s 1;
    -ms-animation: fade-in 4s ease 8s 1;

}

上面的程序我在注释里面都写得很清楚，感兴趣的能够看我写的注释，我以为比较简单，没有难度，可是须要注意浏览器前缀的添加，不然你懂得.utf-8
