Accessibility

 
 

"The power of the Web is in its universality. Access by everyone regardless of disability is essential."

Colas has embraced this policy of active corporate citizenship and is committed to provide you with an accessible website that meets the Double-A conformance requirements of the WCAG 2.0 international accessibility standards.

Accessibility policy

This site has been designed in compliance with the website standards defined by the World Wide Web Consortium (W3C), in particular the Web Content Accessibility Guidelines defined by the Web Accessibility Initiative (WAI). These standards enable the website to be accessed by all, including senior citizens or disabled persons with functional limitations.

A website that complies with accessibility standards benefits all its users. Here a few advantages:

  • the website content is logical and organised by order of importance
  • page display speed is generally increased by 30 to 80%
  • the site does not depend on the web browser used

Compatibility with browsers

This website is compatible with all recent browsers that support HTML 4.01 and CSS 2 techniques. It also complies with the XHTML and CSS vocabulary and grammar recommended by the W3C.

Therefore, it will offer optimum performance with more recent browsers all the while continuing to be accessible to older browsers.

We recommend the use of the browsers below:

  • On Mac.OS.X (Macintosh operating system 10): Opera, Safari, Mozilla Firefox
  • On Windows: Mozilla Firefox, Opera, Internet Explorer 6, HPR (Home Page Reader) 3.0

Browsing principles

  • the Colas logo takes you back to the home page from any page on the website
  • the main menu contains links for accessing the principal content, which is structured and organised into sections
  • the internal menu is specific to each section or internal page of the website
  • a breadcrumb enables you to locate the page you are currently browsing and to move quickly to the upper browsing level. It is placed just after the main menu
  • quick access links (go to menu, go to content) are particularly useful for the visually impaired who can go directly to the editorial area of each page
  • the search engine, placed in the header of each page, provides users with search facilities for the entire website. A search result lists all the pages of the website corresponding to the criteria given.
  • the site map gives an overall representation of all the website’s sections and subsections. It is available in the form of a link at the bottom of each page
  • priority links at the bottom of each page: Accessibility, RSS, Contact, Site Map, Disclaimer.
  • keyboard navigation: use the “Up” and “Down” arrows to move the scroll box, the tabulation key for browsing from link to link, and the “Enter” key to follow an active link

Character size

LSmall-sized characters can make reading on the Internet difficult for some users. On this website, you can make text size bigger or smaller with the “aA” buttons in the header of the editorial area of each page.

If you’re using a wheel mouse, most browsers will enable you to make your text size bigger or smaller by combining the wheel with a keyboard key:

  • Windows: Press the Ctrl key and move the mouse wheel
  • Mac: Press the Apple button and move the mouse wheel
