在 xaringan 标题幻灯片中添加 GitHub 个角

Question

有没有办法使用 CSS 文件在 Xaringan 演示文稿的标题幻灯片上添加 GitHub corner or GitHub ribbon？

我可以将代码直接添加到 HTML 文件中，但是任何演示文稿都是编织的 HTML 被重建。理想情况下，这将是 CSS 的一部分并在 YAML 中控制，但我对 CSS/HTML/JavaScript.

知之甚少

谢谢！

Answer 1

您可以直接将HTML代码混合到markdown源代码中。但是要在标题幻灯片上添加 github 角，需要做一些额外的工作：关闭 auto-generated 角并自己手动创建：

在 YAML 部分设置 seal: false 以关闭 auto-generated 标题幻灯片。
将 github corner 或 github ribbon 的 HTML 代码复制并粘贴到 markdown 源文件中
设置标题幻灯片的其余部分。

示例 (I've also uploaded it on github):

---
title: "Presentation Ninja"
subtitle: "⚔<br/>with xaringan"
author: "Yihui Xie"
date: "2016/12/12 (updated: `r Sys.Date()`)"
output:
  xaringan::moon_reader:
    lib_dir: libs
    nature:
      highlightStyle: github
      highlightLines: true
      countIncrementalSlides: false
    seal: false
---

```{r setup, include=FALSE}
options(htmltools.dir.version = FALSE)
```

class: inverse, center, title-slide, middle

<style>
.title-slide .remark-slide-number {
  display: none;
}
</style>
