xaringan slide separator not separating slides

Question

In this example xaringan presentation, why are both the ## blank page and the leaflet map on the same slide, given I've separated them by the new-slide separator --- ?

---
title: "map test"
output:
  xaringan::moon_reader:
    css: ["default"]
    nature:
      highlightLines: true
---

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```


## blank page

content 

--- 

leaflet page

```{r}
library(leaflet)
leaflet() %>%
  addTiles()

```

Answer 1

Looks like you've got an unintended space after the new slide separator after blank content as "--- ". Remove that space and it'll be recognized as real slide separator:

title: "map test"
output:
  xaringan::moon_reader:
    css: ["default"]
    nature:
      highlightLines: true

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```


## blank page

content 

---

leaflet page

```{r}
library(leaflet)
leaflet() %>%
  addTiles()

```
