## A sunny

I’ve tried ioslide in rmarkdown before. And xaringan today. It looks pretty neat. Here is my quick note of what I have learned

My take on MS ppt / libreoffice impress / ioslide / remark(xaringan):

• MS ppt / libreoffice impress, I’ll have to spend lots of time aligning elements instead of focusing on the content.

• ioslide: neat, but inserting pictures is a pain in the ass. I end up editing the picture resolutions/ inserting modifying code into it. which is contrary to the reason I went for rmarkdown in the first place: care less about the format.

• xaringan: better so far, but a bit complicated than ioslide. I’ll give it a try next time and see if there’s new problems

# basics

## page separator

• use --- to separate pages

• use -- to inherit content in previous page, for incrementally adding points

## page property

• class property: align the entire slides, including left, center,right, top, middle and botom

• layout property is a bit tricky, avoid it.

## export

• exoprting it to a pdf has some issues, use dectape.js as :
system("phantomjs decktape.js slides.html slides.pdf")

## figure

• figures are rendered greater than ioslide1

## layout

• column by column:
---
.pull-left[some stuff]

.pull-right[some other stuff]
---

• footnote:
blablabla<sup>*</sup>

.footnote[[*] Not really. See next page.]
• alignment element
• pics and text works too.
