xaringan: Easy way to change aspect ratio?

Question

I would like to change the aspect ratio of a xaringan presentation to 16:9. I guess it would be possible if I would create a custom css theme. However, this would be somewhat of an overkill for me.

So, is there any really simple way of doing that?

That is super easy since it is already implemented. Just include the following in the YAML (in addition to all the other stuff in your YAML):

output:
  xaringan::moon_reader:
    nature:
      ratio: '16:9'

Here's my default start YAML. Maybe you can tweak that to your desires.

title: "My title"

date: 'Some day 2019'
output:
  xaringan::moon_reader:
    lib_dir: libs
    css: ['default', 'hygge']
    seal: true
    nature:
      ratio: '16:9'
      slideNumberFormat: '%current%' 
      highlightStyle: ir-black
      highlightLines: true
      countIncrementalSlides: false

This is super straight forward. Do you have a link where I could look up all the options? – der_grund Jan 15 '19 at 06:56
A good place to start is the [xaringan wiki](https://github.com/yihui/xaringan/wiki). Also, since xaringan is based on remark.js you could look up that. – ekstroem Jan 15 '19 at 11:18
The wiki looks great. I'll certainly look into that. – der_grund Jan 16 '19 at 07:48
