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：
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。

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
