# Help Me: xaringan / remark.js CSS Themes?

### Yihui Xie / 2017-10-03

Since I have been fearing that too many people will use the same style for xaringan-based slides, which will make xaringan a boring package, I’m looking forward to more user-contributed CSS themes. Currently, the css argument of the output format xaringan::moon_reader takes a default theme, and I hope to bundle more themes in this package, so that users can easily choose a theme they prefer. This is similar to LaTeX beamer themes.

In a previous post “Why xaringan”, I mentioned John Little created a Duke theme, which is a good example of what I’m looking for. I hope such CSS themes could be provided by xaringan (under this directory) so that a user can specify something like css: duke to change the default theme.

I know this will at least help Mine.

Anyone?

P. S. If you really want to kill time, see if you can “reproduce” a Microsoft PowerPoint style with CSS, or LaTeX beamer. The latter may be more challenging. I’ll be waiting for pull requests on Github.
