General principles

This website's graphical architecture is inspired by the principles of Brad Frost's Atomic Design. This method distinguishes five levels of graphic organisation:

Page
The “highest” graphical organisation level is the “page”, which corresponds to the conjunction of every other organizational elements to form a whole unit on which user experience can be measured.

Example: In this website, a “page” typically corresponds to an HTML document associated to a specific route.

Note:

At a “higher” organizational level, we could for instance consider the “website”, just as we could talk about the organization of pages inside a book. However, I consider that these organizational levels “above” that of the “page” are not “graphical”, but require other analytical frameworks.

Template
The “template” prescribes how the different elements are composed in each page.

Example: In our case, the “templates” describe principles such as the position of a navbar on top of the viewport, the presence of links in the footer, and so on. Technically, the “templates” are made possible thanks to Twig's concept of blocks, built with the {extends} instruction.

Organism
An “organism” is a graphical unit of the user interface which gathers multiple functional elements into one coherent group.

Example: the navbar on top of the page, the footer, or the “cards” design.

Molecule
A “molecule” corresponds to one functional unit of the graphical interface, which answers one specific use case.

Example: a line of a form, a button, etc.

Atom
Finally, “atoms” correspond to elementary units of the language (ie. made of a sole HTML element with no children, or with only text nodes), which can be articulated together to form “molecules”.

Example: an <input> field, which can form a molecule when combined with a <label> in a form row.

Templates

Every template for this website are divided in at least 4 main parts:

Navbar
The main navigation is fixed on top of the viewport, in order to always be accessible (except for specific clients such as printers).
Header
The page header contains three graphical organisms:
  1. a breadcrumb to locate the page in relation to the larger architecture of the site
  2. a banner with the title of the page and a short, optional description
  3. the outline linking to the main sections of the page.
Main content
The body of the page is made of multiple <article> elements. They must be identified by a <h2>–<h6> element. They can also be <section> elements. The template for each page adapts the form and content of these elements to fit the page's requirements.
Footer
The footer contains useful links and legal obligations.

These elements form a basis, from which the template of each page can be built. Titles of each article composing the page are automatically added to the outline with JavaScript.

Organisms

Navbar

The main navigation menu is divided in two sub-parts:

Brand
The website's brand with a link to the home page.
Contents
The actual menu, which contains the list of main links, but also action menus to access different translations.

The navbar can take different forms depending on the viewport's size.

  • On small screens, the actual menu is hidden by default, and will only be display when the toggle is checked on. Then, the menu will occupy the whole viewport, sticking the action menu in the bottom.
  • On larger screens, the menu is displayed on one row, with dropdown menus unfolding just below it, and the action menu right-aligned.

Example:

Breadcrumb

The breadcrumb displays links to the sections the current page belongs to. It is a succession of links with automatically added pseudo-elements to indicate the dependence relation.

Example:

Banner

A banner displays an image below some content, with a semi-transparent background to give some contrast in order to keep the content legible.

Example:

Outline

The outline contains links to the main sections of the page (ie. the <article> elements containing a <h2> title)

Example:

Cards

A card is an element with a header, a main content, and sometimes a section listing actions, which takes the form of small cards which can be placed next to each other.

Example:

Vitae omnis eligendi quisquam magnam dolores. Optio quod fuga laudantium tenetur et. Velit amet molestiae unde et ipsa. Nam minima ad eos corporis aut sunt nisi. Nesciunt autem eaque quia.

Fugit veniam provident voluptatum neque facilis repellendus

Quia quisquam et nesciunt nesciunt doloribus illo et.

Corrupti qui non vero omnis ut maiores ut. Reiciendis sequi ut rerum necessitatibus. Eos fuga beatae quos voluptas nostrum libero asperiores.

Quaerat accusantium magnam aut accusantium debitis architecto. Et voluptates molestiae aut vero delectus aperiam. Consequatur voluptatem repellat cupiditate laudantium asperiores similique. Sapiente ad vitae et amet et ut libero.

Timelines

Displays a sequence of chronologically-organized sections.

Example:

Molecules

Forms

.form-row

One row of a form, which contains the actual input as well as helper elements (<label>, etc.), and which occupies the whole width of the container.

Example:
.btn

An element taking the shape of a button (whether it is a <button> or a <a> or any other interactive element).

Example: ut non mollitia reprehenderit
.btn.form-row
Example: omnis dolor illum ut
