How to add headers and linebreaks? - r

Question

I've created a dashboard using flexdashboard with row layout. My first row includes valueboxes and my second row is a leaflet map. How do I add a header above the 2nd row?
As in the code below, I used ### Map header under the 2nd row but that renders as a small title (shown in output). Is there a way to:
Add newlines between the 2 rows?
To format the header to be increase font size and bold?
title: "Dashboard"
output:
flexdashboard::flex_dashboard:
orientation: rows
vertical_layout: scroll
smooth_scroll: true

```{r setup, include=FALSE}
library(flexdashboard)
library(leaflet)
```
Row
-----------------------------------------------------------------------
### Articles per Day
```{r}
valueBox("5 articles", icon = "fa-pencil")
```
### Comments per Day
```{r}
valueBox("10 comments", icon = "fa-comments")
```
Row
-----------------------------------------------------------------------
### Map
```{r}
m <- leaflet() %>%
addTiles() %>%
setView(lng=-77.030137, lat=38.902986, zoom = 16) %>%
addMarkers(lng=-77.030137, lat=38.902986, popup="<b>Hello</b><br><a href='https://www.washingtonpost.com'>-Me</a>")
m
```

Answer 1

You can increase font-size and bold the header ### Map specifically, you can target it by using a css class, say, .custom and apply the css rules for .chart-title class.
And to create space between value-boxes and the map, one option could be increasing the top margin.
