div
#> function (..., .noWS = NULL, .render = NULL)
#> {
#>     validateNoWS(.noWS)
#>     contents <- dots_list(...)
#>     tag("div", contents, .noWS = .noWS, .render = .render)
#> }

I've changed the base branch to #215 as this method will need to be adjusted.

The GHA will not run anymore as the branch is not master.

If the concept is good, we can merge it and have #215 run the checks.
