bscols: Arrange HTML elements or widgets in Bootstrap columns

Description

This helper function makes it easy to put HTML elements side by side. It can be called directly from the console but is especially designed to work in an R Markdown document. Warning: This will bring in all of Bootstrap!

Usage

bscols(..., widths = NA, device = c("xs", "sm", "md", "lg"))

Value

A browsable HTML element.

Arguments

...

htmltools tag objects, lists, text, HTML widgets, or NULL. These arguments should be unnamed.

widths

The number of columns that should be assigned to each of the ... elements (the total number of columns available is always 12). The width vector will be recycled if there are more ... arguments. NA columns will evenly split the remaining columns that are left after the widths are recycled and non-NA values are subtracted.

device

The class of device which is targeted by these widths; with smaller screen sizes the layout will collapse to a one-column, top-to-bottom display instead. xs: never collapse, sm: collapse below 768px, md: 992px, lg: 1200px.

Examples

# \donttest{
library(htmltools)

# If width is unspecified, equal widths will be used
bscols(
  div(style = css(width="100%", height="400px", background_color="red")),
  div(style = css(width="100%", height="400px", background_color="blue"))
)

# Use NA to absorb remaining width
bscols(widths = c(2, NA, NA),
  div(style = css(width="100%", height="400px", background_color="red")),
  div(style = css(width="100%", height="400px", background_color="blue")),
  div(style = css(width="100%", height="400px", background_color="green"))
)

# Recycling widths
bscols(widths = c(2, 4),
  div(style = css(width="100%", height="400px", background_color="red")),
  div(style = css(width="100%", height="400px", background_color="blue")),
  div(style = css(width="100%", height="400px", background_color="red")),
  div(style = css(width="100%", height="400px", background_color="blue"))
)
# }
