Accessibility of the BL City’ZEN Challenge website

“Web accessibility means that websites, tools, and technologies are designed and developed so that people with disabilities can use them. […] It is essential that the Web be accessible in order to provide equal access and equal opportunity to people with diverse abilities.” [Source:]

Berger-Levrault took special care in the design of the website and ensures its development.

To make the website easier to use by all the users, with or without disabilities, regardless the device or the specialized software or equipment they are using, we conformed with a portion of the AA-level criteria of the Web Content Accessibility Guidelines (WCAG) 2.1:

You should be able to:

  • zoom in up to 200% most of the website without problems,
  • navigate most of the website using just a keyboard,
  • navigate most of the website using assistive technology like a screen reader or a magnifier. 


Main navigation

The main navigation is located in the top bar.

There are 4 main sections:

  • About Us
  • Why participate ?
  • The calendar
  • The laureates

The “Apply now” section is separated from the other ones to be highlighted.

Other navigation systems

  • City’ZEN Challenge logo

The City’ZEN Challenge Logo will be displayed on the left heading on all pages. Click on it to return to the landing page of the website.

  • Breadcrumb menu

On all pages except for the landing page, a breadcrumb menu is displayed right under the menu. It allows you to find your way in the website structure. It shows you the path from the home page to the current page and also allows you to go back up in the site tree structure via links.

  • Site map

On all pages, the site map is accessible using a link located in the footer of the page. It allows you to have an overview of the website and to directly access the page or section of your choice.

  • Navigation using a screen reader

A screen reader is a text-to-speech software. It allows you to interact with the computer and listen to what is displayed on the screen in textual form. This tool is often used by visually handicapped and blind people.

We tested the website with the NVDA screen reader. This free software is compatible with Windows and can be downloaded on

Most of the information on the website is accessible with NVDA. And we are working to improve the elements that are not yet returned by the tool.

Below are some shortcuts to navigate through the pages of with NVDA:

  • “Up arrow” and ” down arrow ” to move forward or backward when reading the page
  • “Right arrow” and “left arrow” to move forward or backward one character
  • “h” and “uppercase+h” to move to the next and previous title (title tags H1 to H6)
  • “k” and “maj+k” to navigate to the next and previous link
  • “Ctrl” + “start” to move to the top of the page
  • “Ctrl” + “end” to move to the bottom of the page
  • “Ctrl” to stop NVDA


Colors and pictures

The website offers a high contrast between the color of the font and the color of the background and alternative texts with pictures that conform with display accessibility principles.

Adjusting text size

You can use the zoom feature of your browser to zoom in up to 200%.

PDF documents

The website features a certain number of videos.

Each video is subtitled where necessary. Subtitles allow the deaf, heard-of-hearing or simply persons who do not have access to audio to read the audio information conveyed by the video.

Third party contents

The website uses third party contents. It is not possible to modify them and therefore to guarantee their accessibility. They include the YouTube video player, the cookie script Tarteaucitron, the module hCaptcha, and the plugin Contact Form 7.
