Removing Empty Spaces in R - r

Question

I found this tutorial here that I want to follow: https://beta.rstudioconnect.com/jjallaire/htmlwidgets-showcase-storyboard/htmlwidgets-showcase-storyboard.html
I would like to try and find a way to remove the "empty spaces" that appear in the tabs (e.g. remove the spaces below the red line):
Is there a way to do this in R? I tried to follow the advice recommended in this post over here (Format tab icon size in R flexdashboard) and manually change the font size in hopes that this would work:
---
title: "Untitled"
output:
flexdashboard::flex_dashboard:
orientation: columns
vertical_layout: fill
---
```{r setup, include=FALSE}
library(flexdashboard)
```
<style>
.active {
font-size:15px;
}
</style>
a_tab_name {data-icon="fa-calendar"}
=====================================
Column {data-width=150}
-----------------------------------------------------------------------
### Chart B
```{r}
```
### Chart C
```{r}
```
This seemed to have worked - but is there an automatic way to instruct R to remove all empty spaces in these tabs?
Thank you!

Use height: auto
