比如layout.jade代码如下:

doctype 5
html
   head
     title
       block title
       | My Site
   link(rel="stylesheet", href="/libs/bootstrap2.3/css/bootstrap.min.css")
   link(rel="stylesheet", href="/libs/bootstrap2.3/css/bootstrap-responsive.min.css")
   link(rel="stylesheet", href="/stylesheets/web.css?v=1")

  body
    block content
      div(class="container-fluid")

index.jade代码如下:

extends ../layout
block content
  parent()
  h1 Welcome to .....

jade有木有PHP的twig模板引擎的parent()呢? 在inde.jade继承了content block的所有代码?
