接着之前的[css]我要用css画幅画(五)，由于这个画已经画了很久了，这次一次性加了比较多更新，算是让这幅画告一段落吧。本次的更新包括：

1. 给云增加动画

2. 画了一棵树

3. 树上画了一个苹果，并给苹果增加坠落的动画

其实还有一个TODO List，不过这个List没有也可以算完成，所以这个List可能会无限期搁置：

1. 苹果坠落前左右摇晃一下

2. 苹果落地后滚动几圈

那么进入正题。

这里用到的陌生的css属性包括(直接附上相关的MDN文档链接）：

1. animation-iteration-count - 代表动画执行的次数，默认值为1。值可以是非负整数或infinite关键字， infinite表示执行无数次。

2. animation-direction - 代表关键帧的运行方向，默认值为normal。可选的值共包括：

normal：正向执行，顺序为从from(0%)执行到to(100%)。

reverse：反向执行，顺序为从to(100%)执行到from(0%)。

alternate: 先正向执行再反向执行，也可以理解为奇数次时正向执行，偶数次时反向执行。

alternate-reverse：和alternate相反，先反向执行再正向执行。

3. animation-timing-function - MDN文档说该属性用于定义动画在周期中执行的节奏，我的理解是用于定义动画中帧之间属性的变化速率。默认值是ease(缓动-先加速再减速）。

　　通常可以用简写来指定，常用的简写有缓动（ease,ease-in,ease-out,ease-in-out）和匀速（linear）。除了关键字外，还有稍微特殊的设置：

steps : 语法为 steps(N, target) , N为正整数， target为目标，可以设置start或end（其他值没试过，文档中也没提到）。意思就是，不匀速的分N次到达start。这里举个栗子

cubic-bezier：贝塞尔曲线，语法为 cubic-bezier(x1, y1, x2, y2)，其中四个参数都是小数，可以为负数。通过x和y坐标，定出2个点，通过这两个点，描述一个变化曲线。还没深入研究过，这里暂不多谈。前面的链接是百度百科的，有兴趣可以看看。今天搜到一个不错的网站，可以用来感受一下贝塞尔曲线在动画上的实际效果：http://cubic-bezier.com/#.17,.67,.83,.67 。平时写动画时也可以借助这个网站，不用辛苦的调半天数字。

　　想深入了解这个属性，建议找找更深入的文章，这里只是浅尝辄止：）

4. animation-fill-mode - 用于声明动画执行结束后的目标样式，默认值为none。该值受animation-direction和 animation-iteration-count值的影响。若animation-iteration-count的值是infinite，动画不会结束，则该属性无效。

　　可选值包括：

　　none - 动画结束后，不采用动画关键帧设置的样式。

　　forward - 采用动画最后一帧时的样式

　　backward - 采用动画第一帧时的样式

　　both - 同时采用动画第一帧和最后一帧时的样式。但值有冲突的属性不知道会如何处理。

　　关键帧的设置中，第一帧不一定是from(0%),最后一帧并不一定是to(100%), 具体情况如下表，以下表格是我翻译MDN中得来的：

animation-direction animation-iteration-count 第一帧最后一帧

normal	任何值	0% or from	100% or to
reverse	任何值	100% or to	0% or from
alternate	偶数	0% or from	0% or from
alternate	奇数	0% or from	100% or to
alternate-reverse	偶数	100% or to	100% or to
alternate-reverse	奇数	100% or to	0% or from

PS：以上四个属性和animation-name一样，都可以以逗号分隔设置多个值，每个值用于描述animation-name中相同位置的动画规则。animation-name，关键帧的简要信息可以查看[css]我要用css画幅画(五)

好了，今天就到这里，这幅sun-house的画也告一段落。以后再看看画些啥吧。谢谢阅读。
