Logos
Logos are used for branding web resources. Accessibility requires that the ALT property of the logo's IMG tag is set to the full name of the indicated organization.
A logo for the University of Illinois:
Acceptable markup for this image is:
<img src="images/UILogoCL1L.gif" alt="University of Illinois" />
One may add optionally add the TITLE property in addition to the ALT property. Many visual browsers will display TITLE information when the mouse is hovered over the image.
<img src="images/UILogoCL1L.gif" alt="University of Illinois" title="University of Illinois" />
Unacceptable examples of ALT text are:
- "Illinois", because the description does not uniquely identify the organization nor does the description indicate the image is performing a branding function
- "A white 'I' on a blue background to the left of the word 'Illinois'", because the logo is intended to indicate an organization, and not visual content
