Web Accessibility for Contribute Users

Imagery:

(a) A text equivalent for every non-text element shall be provided (e.g., via “alt”, “longdesc”, or in element content).

Contribute supports "ALT" tags, which are commonly used to annotate images so screen readers can describe imagery on web pages. Here are a few guidelines on when and how to tag your images:

  • When an image is part of the content the ALT tag should describe the image. Examples: "Photo of the main entrance to our building" or "photo of Dr. So-and-so, Dean of Such-and-such" or "Dancers on stage in Carpenter Performing Arts Center".
  • When an image is purely decorative the ALT tag should also describe the image but can be more brief. Examples: "department banner" or "border artwork".
  • When an image performs a function when clicked the ALT tag should indicate the function. Examples include "print this page" or "go to top of page".
  • When an image is a spacer that isn't visible in normal viewing the ALT tag should be null (ALT=""), but since Contribute won't do this..?.

(c) Web pages shall be designed so that all information conveyed with color is also available without color, for example from context or markup.

This rule applies in the same way for images as for text styling above except the information is conveyed through ALT tags.
