Accessibility Standards

Section 508 of the Federal Rehabilitation Act mandates that electronic and information technology is usable by persons with disabilities. One component of the technical standards requires accessibility of web pages. http://www.section508.gov/

Accessibility can be achieved through compliance with WAI guidelines and 508 standards. http://www.w3.org/WAI/ More about web accessibility can be found at http://webaim.org/

Browser Testing

For compliancy, Morrisville websites must function properly in:

  • Internet Explorer 9 +
  • Firefox 3 +
  • Safari
  • Chrome

Testing can be done using the Adobe Browser Lab (https://browserlab.adobe.com/), but it is highly recommended that web pages are tested in each browser for functional and visual compliancy.

Code Validation

Use these tools to check your code for errors and test for accessibility compliancy:

Text Equivalents & ALT Attributes

All images must have an "alt" attribute. An alt tag describes the image for users with screen readers and other assistive technology.

HTML Example:

<img src="mscfootball.jpg"
 alt="Morrisville State College Football" />

Navigation must be text based. Images can coincide with navigation links, but the navigation text must be HTML. Use CSS for navigation markup.

The <table> Tag

Tables should only be used for tabular data, never for display purposes. Tabular data is information that could be recorded in a spreadsheet. Tables should not be used when positioning page elements or to add space - use CSS.

W3Schools is a great resource for beginners in HTML & CSS.

Flash & Javascript

Flash can be memory intensive, is not accessibility compliant and does not work on all devices - therefore Flash should not be used. JavaScript or jQuery may be used for decorative/animation purposes, but the web page must function properly if JavaScript is turned off.

Screen Flickering

Pages shall be designed to avoid causing the screen to flicker with a frequency greater than 2 Hz and lower than 55 Hz (2 to 55 flashes per second).
