Void

zio.blocks.html.Dom.Element.Void
sealed trait Void extends Dom, CssSelectable

A sealed trait for void HTML elements that cannot have children.

Void elements accept attributes but reject children at compile time. They self-close when rendered (e.g., ``, <img src="../../..."/>).

Unlike Element, this trait does not extend Dom.Element so it does not inherit apply(DomModifier*) — only attributes can be applied via apply(Attribute, Attribute*).
