[css]我要用css画幅画(六)_html/css_WEB-ITnose
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。

增加的css如下：
1 .cloud-animate-1 { 2 -webkit-animation-duration: 20s; 3 -webkit-animation-name: cloudMove-1; 4 -webkit-animation-iteration-count: infinite; 5 -webkit-animation-direction: alternate; 6 } 7 8 .cloud-animate-2 { 9 -webkit-animation-duration: 20s;10 -webkit-animation-name: cloudMove-2;11 -webkit-animation-iteration-count: infinite;12 -webkit-animation-direction: alternate;13 }14 15 @-webkit-keyframes cloudMove-1 {16 25% {17 top : 10px;18 }19 20 50% {21 top: 50px;22 }23 24 75% {25 top: 20px; 26 }27 28 to { 29 left: 10% 30 }31 }32 33 @-webkit-keyframes cloudMove-2 {34 25% {35 top : 30px;36 }37 38 50% {39 top: 80px;40 }41 42 75% {43 top: 10px; 44 }45 46 to { 47 left: 85% 48 }49 }

1 .apple { 2 bottom: 360px; 3 height: 60px; 4 position: absolute; 5 right: 480px; 6 width: 60px; 7 z-index: 3; 8 9 -webkit-animation-duration: 1.5s;10 -webkit-animation-delay: 18s;11 -webkit-animation-name: appleDrop;12 -webkit-animation-timing-function: cubic-bezier(0.5, 0.1, 0.85, 0.3);13 -webkit-animation-fill-mode: forwards;14 }15 16 .apple-body {17 background-color: #ff3300; 18 border-radius: 75% 75% 90% 90%;19 height: 50px;20 position: absolute;21 width: 37px;22 z-index: 3;23 }24 25 .apple-left {26 27 }28 29 .apple-right {30 right:2px;31 }32 33 .apple-stalk {34 border: none;35 border-radius: 100%;36 border-right: 3px solid #000;37 height:20px;38 left: 8px;39 position: absolute;40 top:-10px;41 width:20px;42 z-index: 2;43 }44 45 @-webkit-keyframes appleDrop{46 from{47 48 }49 20%{50 51 }52 80%{53 54 }55 to{56 bottom: 35px;57 }58 }
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：
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：
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：
| 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。
