shadow {html5}

Generate the <shadow> HTML tag.

Description

The <shadow> HTML element—an obsolete part of the Web Components technology suite—was intended to be used as a shadow DOM insertion point. You might have used it if you have created multiple shadow roots under a shadow host. It is not useful in ordinary HTML.

Usage

shadow(
  ...,
  attr = NULL,
  separate = FALSE,
  collapse = "",
  formatted = html5_vars$formatted
)

Arguments

...

A string or vector of content to pass to the tag.

attr

A named list or named vector, names are attribute names and values are attribute values.

separate

TRUE/FALSE, If TRUE, returns separate tags for each item of ...; if FALSE, returns one tag with the items of ... in the tag content.

collapse

A string. If NULL, returns a vector the same length as ... instead of collapsing the tags into one string.

formatted

TRUE/FALSE, if TRUE, HTML will be generated with indents and new lines for readability at the cost of performance. Controlled by setting the environment variable html5_vars$formatted <- TRUE/FALSE
