A Bootstrap theme created with bs_theme() is comprised of many Sass layers. bs_remove() and bs_retrieve() allow you to remove or retrieve an individual layer, either to reduce the size of the compiled CSS or to extract styles from a theme.

Usage

bs_remove(theme, ids = character(0))

bs_retrieve(theme, ids = character(0), include_unnamed = TRUE)

Arguments

theme

A bs_theme() object.

ids

a character vector of ids

include_unnamed

whether or not to include unnamed sass::sass_layer()s (e.g., Bootstrap Sass variables, functions, and mixins).

Value

Returns a modified bs_theme() object.
