[SERVER]
A standard, express-based Node.js web site. Since the site is completely static
it could have as well been rendered to HTML, CSS and client-side JS once.

The content is split into five tabs. Each tab is represented by an object with
the following properties:

  * title: The single-word title of the tab
  * longTitle: The title of the HTML document representing the tab
  * (subs: An array of similar objects, representing subpages)

subpages may have additional properties. Subpages are defined in separate JS
files in the `subs` directory: If no file corresponding to a tab exists, the
tab has no subpages.

HTML is generated from Pug templates in the `views` directory. Every tab has
an own template file, there is a layout file and tabs with subpages have an
additional `tab_subs.pug` file for the subpage content rendering. This setup
works best where the whole tab content is visible on subpages as well.

The response sent to a client heavily depends on the passed `Accept` header:
  * If the `Accept` header includes standard HTML, the full page with layout and
    tab template is rendered. If a subpage has been requested, the tab template
    has to include and render the subpage template appropriatly.
  * If the `Accept` header does not include HTML, but includes
    `application/prs.de.adrianlang.hire.tab`, the tab template is rendered
    without the layout.
  * Finally, if the `Accept` header does not include HTML, but
    `application/prs.de.adrianlang.hire.focus`, the tab’s subpage template is
    directly rendered, without layout or tab template.

Accordingly, the response sets `Vary: Accept` and the `Content-Type` as
requested.

[CLIENT CODE]
The client-side JavaScript is only active in modern browsers with HTML5’s
history manipulation API available. In such environments, it augments links
such that internal navigation works without page reloads by cleverly retrieving
the needed page content via XHR and inserting it in-place. document location,
title and browsing history are handled correctly. The script makes use of the
aforementioned personal mime types to specify which representation of a tab or
subpage it needs. No library is used for DOM manipulation or XHR.

[HTML]
The HTML uses HTML5‘s new, semantic elements. It’s quite straight-forward and
contains no additional markup for styling purposes.

[STYLE]
I’m using Less for a SMACCS-like modularization. The CSS targets current
browsers: IE > 7, Firefox > 3, Opera > 9.0. Limiting techniques are box-sizing,
inline-block and media queries. background-size does not work in IE < 9, but
it’s a minor issue.

The layout is a grid with 4 columns, each having a spacing of 0.8333% of the
page width to the left and right. The grid has a padding of 10% on the left and
right, which leaves an area of 80% for the content. Vertically, the elements
are aligned on 0.5em rows. The maximum width of the whole page is 48em.
