This site is based on Web standards so as to be accessible to disabled people (partial or complete blindness, motor or mental disabilities, etc.) while being compatible with technical aid (Braille script, screen reader, mouseless navigation, etc.).
The site is built with a system of alternative style sheets so that you can consult and print the site according to your settings and browsing preferences.
W3C standards respected
The HTML code complies with the specification HTML5. It is tested using the HTML W3C code validator ; the CSS code complies with the specification CSS3.
A text equivalent is provided through the significant image alt attribute, when they are not precisely described in the text they illustrate. The insignificant image "alt attribute is empty. The page layout does not use invisible images ; images are only used when there is no HTML X element for giving the information concerned.
Structure and presentation
By using CSS positioning properties, totally separating presentation and content, documents remain in coherent order when not displayed as CSS :
- The title, the contents, the menus ;
- The site is organised in sections with articles according to themes ;
- The layout of the site is based exclusively on external style sheets ;
- the pages are structured using h1.h6 titles, used in the appropriate order ;
- information in the form of a list of items is tagged using ul, ol and dl elements ;
- The presentation style is coherent over the whole site because a single style sheet is used.
Navigation and links
The site map is accessible from each page ; the browser menus reflect the information structure. They allow permanent access to the entire site ; the matching links are grouped together logically and structurally. Adjacent links are separated by printable characters so as to avoid confusion by remote technologies.
