Module: Canon::PrettyPrinter::HtmlVoidElements

Defined in:
lib/canon/pretty_printer/html_void_elements.rb

Overview

The 14 HTML5 void elements — those whose start tag may stand alone (with no end tag) and which cannot have any content. Every other element with no children must be written as <tag></tag> in HTML; writing <a/> is illegal HTML and is parsed as <a> (start tag only).
