一、最终效果

 

需求:gift图片的小动画每隔2s执行一次。

需求就一句话,我们看一下实现过程。

二、实现过程

1、网页结构

2、原始动画

原始动画效果为:鼠标hover上去出现动画。

动画样式如下:

<span style="color: #008000;">/*</span><span style="color: #008000;">动画</span><span style="color: #008000;">*/</span><span style="color: #800000;">
    .ico:hover</span>{<span style="color: #ff0000;">
    -webkit-animation</span>:<span style="color: #0000ff;"> Tada 1s both</span>;<span style="color: #ff0000;">
    -moz-animation</span>:<span style="color: #0000ff;"> Tada 1s both</span>;<span style="color: #ff0000;">
    -ms-animation</span>:<span style="color: #0000ff;"> Tada 1s both</span>;<span style="color: #ff0000;">
    animation</span>:<span style="color: #0000ff;"> Tada 1s both
</span>}
<span style="color: #008000;">/*</span><span style="color: #008000;">浏览器兼容性部分略过</span><span style="color: #008000;">*/</span><span style="color: #800000;">
@keyframes Tada </span>{<span style="color: #ff0000;">
    0% {
        transform</span>:<span style="color: #0000ff;"> scale(1)</span>;<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(1)
    </span>}<span style="color: #800000;">

    10%,20% </span>{<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(0.9) rotate(-3deg)</span>;<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(0.9) rotate(-3deg)
    </span>}<span style="color: #800000;">

    30%,50%,70%,90% </span>{<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(1.1) rotate(3deg)</span>;<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(1.1) rotate(3deg)

    40%,60%,80% </span>{<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(1.1) rotate(-3deg)</span>;<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(1.1) rotate(-3deg)
    </span>}<span style="color: #800000;">

    </span>}<span style="color: #800000;">
}</span>

效果:鼠标hover上去gift图片会动一动。

3、实现变化后的需求

需求变动,要求不再是hover上去展示动画,而是每隔2s展示一次动画。

思路:不需要hover上去出现动画,就把hover去掉,每隔2s显示一次动画,很容易想到延迟2s,然后动画一直执行。

此时相关样式变成:

<span style="color: #800000;">.ico</span>{<span style="color: #ff0000;">
-webkit-animation</span>:<span style="color: #0000ff;"> Tada 1s  2s both infinite</span>;<span style="color: #ff0000;">
-moz-animation</span>:<span style="color: #0000ff;"> Tada 1s 2s both infinite</span>;<span style="color: #ff0000;">
-ms-animation</span>:<span style="color: #0000ff;"> Tada 1s 2s both infinite</span>;<span style="color: #ff0000;">
animation</span>:<span style="color: #0000ff;"> Tada 1s 2s both infinite</span>;
}

但是显示的效果是:页面加载第一次出现动画会延迟2s,后面的动画将不再有延迟。如下,这是不符合需求的。

为了看出效果,下图为延迟6s的效果。

此时换种思路,不要延迟执行动画,而是动画的效果本身就是前2s元素不动,后1s是元素动,然后一直循环执行。 这样在视觉上就会看起来是延迟2s执行1s动画。

计算一下,原来的百分比节点变成了多少。

将动画总时长变成3s,用计算出的百分比替换原来的百分比,代码如下:

<span style="color: #800000;">.ico</span>{<span style="color: #ff0000;">
    -webkit-animation</span>:<span style="color: #0000ff;"> Tada 3s both infinite</span>;<span style="color: #ff0000;">
    -moz-animation</span>:<span style="color: #0000ff;"> Tada 3s both infinite</span>;<span style="color: #ff0000;">
    -ms-animation</span>:<span style="color: #0000ff;"> Tada 3s both infinite</span>;<span style="color: #ff0000;">
    animation</span>:<span style="color: #0000ff;"> Tada 3s both infinite</span>;
}<span style="color: #800000;">
@keyframes Tada </span>{<span style="color: #ff0000;">
    0% {
        transform</span>:<span style="color: #0000ff;"> scale(1)</span>;<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(1)
    </span>}<span style="color: #800000;">

    70%,73%</span>{<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(0.9) rotate(-3deg)</span>;<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(0.9) rotate(-3deg)
    </span>}<span style="color: #800000;">

    77%,83%,90%,97%  </span>{<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(1.1) rotate(3deg)</span>;<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(1.1) rotate(3deg)
    </span>}<span style="color: #800000;">

    80%,87%,93%</span>{<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(1.1) rotate(-3deg)</span>;<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(1.1) rotate(-3deg)
    </span>}<span style="color: #800000;">

    100% </span>{<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(1) rotate(0)</span>;<span style="color: #ff0000;">
        transform</span>:<span style="color: #0000ff;"> scale(1) rotate(0)
    </span>}<span style="color: #800000;">
