/// The `hide` function allows you to hide content while the layout still 'sees'
/// it. This is useful to create whitespace that is exactly as large as some
/// content. It may also be useful to redact content because its arguments are
/// not included in the output.
///
/// # Example
/// ```example
/// Hello Jane \
/// #hide[Hello] Joe
/// ```
#[elem(Show)]
pub struct HideElem {
/// The content to hide.
