Builds a head tag. Adds a meta
tag inside with Content-Type
set to text/html; charset=utf-8
.
# File lib/markaby/builder_tags.rb, line 29 def head(*args, &block) tag!(:head, *args) do tag!(:meta, "http-equiv" => "Content-Type", "content" => "text/html; charset=utf-8") if @output_meta_tag instance_eval(&block) end end
Every HTML tag method goes through an #html_tag call. So, calling
div
is equivalent to calling html_tag(:div)
. All
HTML tags in Markaby's list are given generated wrappers for this
method.
If the @auto_validation setting is on, this method will check for many common mistakes which could lead to invalid XHTML.
# File lib/markaby/builder_tags.rb, line 17 def html_tag(sym, *args, &block) if @auto_validation && @tagset.self_closing.include?(sym) && block raise InvalidXhtmlError, "the `#{sym}' element is self-closing, please remove the block" elsif args.empty? && !block CssProxy.new(self, @streams.last, sym) else tag!(sym, *args, &block) end end
Builds an html tag with XHTML 1.0 Frameset doctype instead.
# File lib/markaby/builder_tags.rb, line 51 def xhtml_frameset(attrs = {}, &block) self.tagset = Markaby::XHTMLFrameset xhtml_html(attrs, &block) end
Builds an html tag with XHTML 1.0 Strict doctype instead.
# File lib/markaby/builder_tags.rb, line 45 def xhtml_strict(attrs = {}, &block) self.tagset = Markaby::XHTMLStrict xhtml_html(attrs, &block) end
Builds an html tag. An XML 1.0 instruction and an XHTML 1.0 Transitional
doctype are prepended. Also assumes :xmlns =>
"http://www.w3.org/1999/xhtml", :lang =>
"en"
.
# File lib/markaby/builder_tags.rb, line 39 def xhtml_transitional(attrs = {}, &block) self.tagset = Markaby::XHTMLTransitional xhtml_html(attrs, &block) end
# File lib/markaby/builder_tags.rb, line 58 def xhtml_html(attrs = {}, &block) instruct! if @output_xml_instruction declare!(:DOCTYPE, :html, :PUBLIC, *tagset.doctype) tag!(:html, @root_attributes.merge(attrs), &block) end
