Working with ALT tags

Text equivalents in the form of ALT tags can be provided for buttons, images, and animations in the program. The accessibility requirement not only necessitates that text equivalents must be provided, but also implies that the alternative text must be properly implemented. Follow these guidelines when providing alternative text:

ALT tags in the program are created from the object’s name as it is listed in the Title Explorer. This is the same name that appears in the Name field of the object’s properties. Object names serving also as the ALT tags should be limited to 156 characters.

If you cannot describe the animation, image, or button in less than 156 characters, use a textual caption, hidden description, or a pop-up window to provide the object’s description.

If images, animations or buttons within your content are of no informational value or are used merely for decoration, the objects should have empty ALT tags. This enables screen readers to ignore the object and prevents the screen reader from announcing any unnecessary information to the user.

Buttons intended to be ignored should be omitted entirely from the title, and images that have an empty ALT tag cannot have actions attached to them.
