Compliance with standards
From the outset, the W3C, the organization responsible for Internet standardization, has incorporated the concept of accessibility into its work. The most visible part of this work is the Accessibility Initiative, which has produced a specification for Web content, the WCAG.
Alternative versions of the site
Print-optimized version
When you print a page, all the site's navigation elements will be hidden so that you can print only the useful content of your information: on all browsers, in the menu bar at the top of the browser, go to File > Print (shortcut: Ctrl + P).
Navigation help
Tab navigation
Within the same page, you can move from element to element (links, form elements, etc.) by pressing Tab and repeating until you select the desired element, then pressing Enter.
Main menu
The main menu makes it easy to explore the site's main sections. Hovering over a heading displays its sub-menu, giving direct access to the pages within that heading. When you are in a page, the pages of the same heading are displayed in the contextual column and can be accessed at any time.
The main menu is accessed via the Tab key. To navigate the menu, use the arrow keys to select the desired item, then press Enter to confirm.
Breadcrumb trail
A breadcrumb trail is a navigation tool that helps you find your way around the site. Displayed at the top of the main content, it allows you to find your way through the tree structure to the page you're viewing, and to return easily to higher levels. It takes the form of Home > Current section > Current sub-section > Page displayed.
Site map
The site map gives visitors a quick overview of the site's entire content, with access to each page.
