Content: tables, media and typography • bootstrict

library(shiny)
library(bootstrict)

These are the static “content” widgets: tables, images and figures, blockquotes, display typography, and lists — plus a few small helpers. None report state to the server; they are pure UI.

Tables

bs_table() renders a faithful Bootstrap <table class="table">. Pass a data frame or matrix as the first argument and it builds the header and body for you; pass tag children instead to hand-build the rows.

bs_table(
  data = NULL,
  ...,                 # manual children when `data` is NULL
  striped = FALSE,     # TRUE / "rows", or "columns"
  bordered = FALSE,    # borders on all sides
  borderless = FALSE,  # remove all borders
  hover = FALSE,       # hover highlight
  small = FALSE,       # condensed padding
  variant = NULL,      # a theme colour for the whole table
  responsive = FALSE,  # TRUE, or a breakpoint "sm"/"md"/… for horizontal scroll
  align = NULL,        # vertical alignment: "middle"/"top"/"bottom"
  caption = NULL,
  caption_top = FALSE, # put the caption above the table
  head_variant = NULL, # a theme colour for the <thead>
  group_divider = FALSE, # thicker border under the header
  row_variant = NULL,  # per-row theme colour, recycled; NA leaves a row plain
  rownames = NULL,     # row names as the reference <th scope="row">
  class = NULL
)

The most common form — a styled data-frame table:

bs_table(head(mtcars), striped = TRUE, hover = TRUE)

The accented variants from the Bootstrap tables page are arguments rather than classes you have to remember, and they compose:

bs_table(
  head(mtcars, 4),
  head_variant = "dark",
  group_divider = TRUE,
  row_variant = c(NA, "success", NA, "danger"),
  caption = "Four cars",
  caption_top = TRUE
)

row_variant is recycled to the number of rows, so a single value colours them all, and NA leaves a row alone. "active" is accepted alongside the theme colours.

responsive = TRUE wraps the table so it scrolls horizontally on narrow screens (or pass a breakpoint to only do so below it):

bs_table(
  df,
  striped = TRUE,
  small = TRUE,
  responsive = TRUE,
  caption = "24 matching events"
)

Images

bs_img() is a Bootstrap <img> with the usual responsive utilities.

bs_img(
  src,
  ...,
  fluid = FALSE,      # .img-fluid — scale down to fit the parent
  thumbnail = FALSE,  # .img-thumbnail — rounded bordered frame
  rounded = FALSE,    # rounded corners
  object_fit = NULL,  # "contain"/"cover"/"fill"/"scale"/"none" (5.3)
  alt = NULL,
  class = NULL
)

bs_img("logo.png", alt = "Logo", fluid = TRUE)

Figures

A figure groups an image with a caption. Use bs_figure_img() and bs_figure_caption() inside bs_figure():

bs_figure(
  bs_figure_img("photo.jpg", alt = "A photo"),
  bs_figure_caption("A caption for the image.")
)

Blockquotes

bs_blockquote() renders a Bootstrap .blockquote inside a <figure>, with an optional attribution footer:

bs_blockquote(
  "The data set gives the locations of 1000 seismic events of MB > 4.0.",
  footer = "R datasets documentation"
)

Display typography

Two constructors cover Bootstrap’s opinionated typographic accents.

bs_display_heading() is a large, prominent heading; level (1–6) sets both the size (.display-{level}) and the heading element:

bs_display_heading("Seismic activity, Fiji region", level = 2)

bs_lead() is a standout opening paragraph (.lead):

bs_lead("1,000 events of magnitude 4.0 and above, recorded since 1964.")

Lists

bs_list_unstyled() strips the default list styling; each unnamed argument becomes an <li>. bs_list_inline() lays the items out horizontally.

bs_list_unstyled("First", "Second", "Third")
bs_list_inline("One", "Two", "Three")

You can also pass explicit tags$li() children when an item needs richer content:

bs_list_unstyled(
  tags$li(tags$code("bootstrict_theme()"), " — the designer's sheet is the theme"),
  tags$li(tags$code("bs_offcanvas()"), " — the filter drawer")
)

(For an interactive, selectable list, use bs_list_group() — see Components.)

Small helpers

A handful of one-off utilities round out the content toolkit:

bs_icon_link() — the Bootstrap 5.3 icon-link: an inline-flex <a> pairing an icon with text. hover = TRUE nudges the icon on hover.
```
bs_icon_link("Documentation", href = "#")
```
bs_ratio() — wraps an embedded element (an <iframe>, a video) so it keeps a fixed aspect ratio. ratio is "1x1", "4x3", "16x9" or "21x9".
```
bs_ratio(tags$iframe(src = "https://example.com"), ratio = "16x9")
```
bs_vr() — a vertical divider, the vertical counterpart of <hr>. Handy between items in an bs_hstack().
```
bs_hstack(gap = 2, "Left", bs_vr(), "Right")
```
bs_visually_hidden() — content available to assistive technology but hidden from sighted users.
```
bs_visually_hidden("Loading, please wait")
```
