How to display 2 flexdashboard gauges side by side in Rmarkdown HTML?

Question

I have two flexdashboard gauges that I would like to plot side-by-side in an Rmarkdown -> html file. The file is NOT meant to be a flexdashboard, just trying to use the pretty gauges from that package.

```{r setup, include=FALSE}
library(flexdashboard)
gauge1_data <- 95
gauge2_data <- 63
max_data <- 100
```

## Gauges
```{r gauge, fig.width=2, fig.height=2, fig.cap='Cap1'}
gauge(round(100*(1.0*gauge1_data)/max_data,2),0,100, symbol = '%', label= "Non-Stops: Tile 1", gaugeSectors(
  success = c(80, 100), warning = c(40, 79), danger = c(0, 39)))
```
```{r gauge2, fig.width=2, fig.height=2, fig.cap='Cap1'}
p0 <- gauge(round(100*(1.0*gauge2_data)/max_data,2),0,100, symbol = '%', label= "Full Cabin Match: Tile 1", gaugeSectors(
  success = c(80, 100), warning = c(40, 79), danger = c(0, 39)))
```

^{I like big gauges and I cannot lie.}

Surprisingly, I'm having a hard time getting them side by side. Tried to use library(gridExtra) but it only likes to arrange things called grobs. Gauges are class htmlwidget & gauge.

Also tried {r out.width=c('500px', '300px'), fig.show='hold'} and cramming them both in the same chunk but got an error.

I'd appreciate any suggestions.

The gauges in flexdashboard are specifically for use with the flexdashboard layout system and won't generally work as expected in other formats (that's why the widget is part of flexdashboard rather than in a standalone package).
