\arguments{
\item{_tag_name}{HTML tag name}
\item{varArgs}{List of attributes and children of the element. Named list
items become attributes, and unnamed list items become children. Valid
children are tags, single-character character vectors (which become text
nodes), and raw HTML (see \code{\link{HTML}}). You can also pass lists that
contain tags, text nodes, and HTML.}
\item{tag}{A tag to append child elements to.}
\item{child}{A child element to append to a parent tag.}
\item{...}{Unnamed items that comprise this list of tags.}
\item{list}{An optional list of elements. Can be used with or instead of the
\code{...} items.}
}
\value{
An HTML tag object that can be rendered as HTML using
\code{\link[base]{as.character}()}.
}
\description{
\code{tag()} creates an HTML tag definition. Note that all of the valid HTML5
tags are already defined in the \code{\link{tags}} environment so these
functions should only be used to generate additional tags.
\code{tagAppendChild()} and \code{tagList()} are for supporting package
authors who wish to create their own sets of tags; see the contents of
bootstrap.R for examples.

\examples{
tagList(tags$h1("Title"),
tags$h2("Header text"),

# Can also convert a regular list to a tagList (internal data structure isn't
# exactly the same, but when rendered to HTML, the output is the same).
x <- list(tags$h1("Title"),
tags$h2("Header text"),
tags$p("Text here"))
