Overview

About

Maintained by Carson SievertCRAN page ↗GitHub ↗Website ↗Issues ↗Declared funder: Posit Software, PBC

Simplifies custom 'CSS' styling of both 'shiny' and 'rmarkdown' via 'Bootstrap' 'Sass'. Supports 'Bootstrap' 3, 4 and 5 as well as their various 'Bootswatch' themes. An interactive widget is also provided for previewing themes in real time.

Changes in 0.12.0

New features

Added offcanvas() to create Bootstrap offcanvas panels that slide in from an edge of the viewport. Panels can be revealed by a trigger element in the UI or controlled from the server with show_offcanvas(), hide_offcanvas(), and toggle_offcanvas(). (#1328)

Documentation

layout_columns() and layout_column_wrap() now describe their CSS length inputs with concrete examples. (@LeonidasZhak #1300)

Bug fixes

Fixed dynamically-rendered outputs (e.g. uiOutput()) failing to render inside a title-less popover() or tooltip(), caused by an upstream Shiny change. A temporary CSS workaround restores rendering. (#1326)
Fixed label-to-options spacing on shiny::radioButtons() and shiny::checkboxGroupInput() in Bootstrap 5, where a Shiny rule was overriding the bslib fix. (#1308)
Fixed the resize handle indicator position for position = "right" sidebars, which now correctly appears at the inner boundary of the sidebar handle. (#1322)
Allow users to directly grab the sidebar handle to resize the sidebar. (#1331)

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("bslib", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("rstudio/bslib")

Development version from rstudio/bslib. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-bslib

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-bslib

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-bslib

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
