目录：

• 安装
• 加成
• 数据属性
• 选项
• API方法
• 事件

如何使用它:

1.下载软件包，并在HTML文档中加载必要的JavaScript和CSS文件。

<link rel="stylesheet" href="dist/reveal.css" />
<script src="dist/reveal.js"></script>

2.在文档中加载您选择的主题：

<link rel="stylesheet" href="dist/theme/beige.css" />
<link rel="stylesheet" href="dist/theme/black.css" />
<link rel="stylesheet" href="dist/theme/blood.css" />
<link rel="stylesheet" href="dist/theme/league.css" />
<link rel="stylesheet" href="dist/theme/moon.css" />
<link rel="stylesheet" href="dist/theme/night.css" />
<link rel="stylesheet" href="dist/theme/serif.css" />
<link rel="stylesheet" href="dist/theme/simple.css" />
<link rel="stylesheet" href="dist/theme/sky.css" />
<link rel="stylesheet" href="dist/theme/solarized.css" />
<link rel="stylesheet" href="dist/theme/white.css" />

3.在文档中加载您选择的插件：

<!-- Syntax highlighting -->
<script src="plugin/highlight/highlight.js"></script>

<!-- Write content using Markdown -->
<script src="plugin/markdown/markdown.js"></script>

<!-- Render math equations -->
<script src="plugin/math/math.js"></script>

<!-- Show a speaker view in a separate window -->
<script src="plugin/notes/notes.js"></script>

<!-- Press CTRL+Shift+F to search slide content -->
<script src="plugin/highlight/highlight.js"></script>

<!-- Alt+click to zoom in on elements -->
<script src="plugin/zoom/zoom.js"></script>

4.您也可以使用NPM安装和导入reveal.js。

# Yarn
$ yarn add reveal.js

# NPM
$ npm i reveal.js --save

import Reveal from 'reveal.js';
import Markdown from 'reveal.js/plugin/markdown/markdown.esm.js';
// .. more plugins here

5.初始化reveal.js，我们就可以开始了。

let instance = new Reveal({
    // ... options here ...
})
instance.initialize();

6.根据您的需要加载一个外部版本。所有可能的扩展：

• 突出：Synax荧光笔。
• 降价：处理演示文稿内部降价的解析以及外部降价文档的加载。
• 数学：允许在reveal.js幻灯片中渲染数学方程。本质上是MathJax的薄包装。
• 笔记：处理reveal.js注释窗口的打开和同步。
• 搜索：处理在幻灯片中的任何位置查找文本字符串，并通过导航到该幻灯片并突出显示来向用户显示下一次出现的内容。
• 缩放：将放大/缩小动画应用于幻灯片

// Browser
instance.initialize({
  plugins: [ RevealMarkdown ]
});

// ES Module
instance.initialize({
  plugins: [ Markdown ]
});

7.在演示文稿中插入您自己的幻灯片并完成。

<div class="reveal">
  <div class="slides">
    <section>Slide 1</section>
    <section>
      <section>Vertical Slide 2-1</section>
      <section>Vertical Slide 2-2</section>
    </section>
    <section>Slide 3</section>
    ...
  </div>
</div>

8.或者使用Markdown编写内容。

<section data-markdown>
  <textarea data-template>
    Markdown Here
  </textarea>
</section>

<section data-markdown="example.md"
         data-separator="^\n\n\n"
         data-separator-vertical="^\n\n"
         data-separator-notes="^Note:"
         data-charset="iso-8859-15">
         Or load from an external Markdown file
</section>

<section data-markdown>
  <script type="text/template">
    - Fragment 1
    - Fragment 2
    - Fragment 3
  </script>
</section>

<section data-markdown>
  <script type="text/template">
  <!-- .slide: data-background="#ff0000" -->
    Markdown Here
  </script>
</section>

9.可用于自定义每张幻灯片的HTML数据属性。

• 修正：当片段被隐藏时，片段内部的视频/音频现在停止播放。
• 修正了：Markdown现在被广告中默认的分隔符（---）分割成单独的幻灯片。
• 已修复：r-fit-text布局帮助程序现在可以在PDF导出中正确调整文本大小。
• 修复了某些幻灯片特定的转换被全局转换设置错误覆盖的问题。
• 已修复：has dark background helper类现在可以在使用命名颜色作为数据背景颜色时工作。

版本4.1.0（2020-10-12）

• 新增：将数据可见性=“隐藏”添加到幻灯片中，以将其隐藏在视图之外
• 新增：添加r-fit-text类，使文本节点尽可能大，而不会溢出幻灯片。
• 配置的幻灯片宽度/高度现在显示为CSS变量（--幻灯片宽度/--幻灯片高度）。
• shuffle配置选项现在也可以打乱垂直幻灯片。
• 现在，所有主题都将基于当前幻灯片背景颜色反转文本颜色。
• 在npm包中包含/css和/js。
• Bugfixed（错误修复）

• 启用JavaScript构建的缓存，使后续构建的速度提高约50%。
• 在自动滑动演示中，数据自动滑动属性现在优先于<video>持续时间的自动检测。
• 删除打印到PDF时过于热心的重置样式。
• Reveal.configure和Reveal.isReady现在在预先初始化的reval.js API中可用，以匹配v3.x行为。
• 切换到从CDN提供演示演示资产。
