+# Marp：用 Markdown「写」PPT 的新选择
+- Marp
+ - Markdown --> PPT
+
+---
+# 需求
+- 制作视频之前，写文案
+ - 工作量少，简单
+ - 不想写一堆代码
+ - 翻页效果，即可。
+ - 有动画更好
+- 简洁，清晰明了
+ - 不想做得花里胡哨
+- 视频 [【新技能】Marp 使用 Markdown 制作 PPT ， 电脑不用安装PowerPoint](https://www.bilibili.com/video/BV17v411T7wH/)
+---
+- 参考
+ - [Marp：用 Markdown「写」PPT 的新选择](https://sspai.com/post/55718)
+ - 前往 VSCode 的网站 下载并安装 VSCode 本体，
+ - 然后在左侧的插件栏中搜索并安装 Marp for VS Code。
+ - 为了获得更好的 Markdown 编辑体验，大家不妨再安装一个叫做 Markdown All in One 的插件，然后就可以开始愉快地使用 Marp 了。
+ - 使用 Markdown 预览功能，确认无误后，再导出
+ - toggle打开或关闭特效
+ - marp: true
+ - 缺点，没有动画特效
+- Demo
+ - https://yhatt-marp-cli-example.netlify.app/#1
+ - 代码 https://github.com/yhatt/marp-cli-example
+
+# reveal.js 官网 https://revealjs.com/
+---
+编辑完成后，通过编辑器右上角的 Marp 图标按钮就可以调出 Export slide deck 命令并导出幻灯片了。Marp 插件目前支持导出 HTML 和 PDF 格式，另外可以将首页导出为 PNG 或 JPEG 格式的图片。
+
+需要注意的是，目前导出 PDF 或者图片时需要依赖 Chromium 内核的浏览器。最终的导出效果与预览时看到的相同。
