Set default & require values with method signatures

Ruby method signatures enforce required data and sets defaults

Set default values in arguments

class TailwindNav < Phlex::HTML
  def initialize(title: "Main Menu")
    @title = title
  end

  def view_template(&content)
    h2(class: "font-bold") { @title }
    nav(class: "flex flex-row gap-4", &content)
  end

  def item(url, &content)
    a(href: url, class: "text-underline", &content)
  end
end

Override default method value

render TailwindNav.new title: "Site Menu" do |it|
  it.item("/") { "Home" }
  it.item("/about") { "About" }
  it.item("/contact") { "Contact" }
end
