a11y-menu

The goal of this project is to bring to life in a single JS file an accessibility file, self loading. It should bring these functionalities :

• ability to increase/decrease the font size, without zooming on the images, from 50% to 150% of the actual font size
• ability to fix single letter horizontal space to a single value, increasing readability for ppl that have difficulties to read, reading letter to letter
• ability to toggle the font family, to use at least one readable "sans" font, actually Open Sans (that could change in the future) ; and at least one specific font, OpenDyslexic
• this menu should insert at the top of the page, expanding full width (to be sure we don't break the current design of the page)

How to use it

You need to import the 2 libs Cookies js and jQuery :

<script src="https://cdn.jsdelivr.net/npm/js-cookie@3.0.5/dist/js.cookie.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.7.1/jquery.min.js" integrity="sha512-v2CJ7UaYy4JwqLDIrZUI/4hqeoQieOmAZNXBeQyjo21dadnwR+8ZaIJVT8EE2iyI61OV8e6M8PP2/4hpQINQ/g==" crossorigin="anonymous" referrerpolicy="no-referrer"></script>

Then you can import a11y-helper.js and a11y-helper.css :

<script src="/path/to/a11y_helper.js"></script>
<link rel="stylesheet" href="/path/to/a11y_helper.css" />

or use the CDN :

<script src="https://cdn.jsdelivr.net/gh/gautiermichelin/a11y@master/a11y_helper.js"></script>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/gh/gautiermichelin/a11y@master/a11y_helper.css" />

Fix your CSS

Sometimes you have classes that "stick" on the top of the screen, for example a navbar or a sticky header. You can fix this by adding a class to the element that you want to fix, and add this class to the CSS file.

This is the actual CSS for the navbar :

.fixed-top {
  position: fixed;
  top: 0;
  right: 0;
  left: 0;
  z-index: 1030;
}

Now, you need to make it go down for 100px to have enough space for the top accessibility menu.

.fixed-top {
  position: fixed;
  top: 0;
  right: 0;
  left: 0;
  z-index: 1030;
}
.accessibility-menu-open .fixed-top {
  top: 100px;
}

TODO

• remove jQuery dependency
• inject the CSS within the JS to have a single file
• embed cookies lib and use the no-conflict mode : https://github.com/js-cookie/js-cookie#namespace-conflicts
