This technique relates to:
- Success Criterion 1.1.1: Non-text Content (Sufficient)
- Success Criterion 1.2.3: Audio Description or Media Alternative (Prerecorded) (Sufficient as a way to meet an unwritten technique)
- Success Criterion 1.2.8: Media Alternative (Prerecorded) (Sufficient as a way to meet an unwritten technique)
The objective of this technique is to provide a text alternative for content rendered
using the object element. The body of the
object element can be used to provide a
complete text alternative for the object, or may contain additional non-text content
Fallback content for the
object element is only available to the user when the media loaded by the element is not
rendered by the user agent, because the user agent does not support the media technology
or the user has instructed the user agent not to render that technology. In these
situations, the fallback content will be presented to the user. If the media is rendered
without the fallback content, the media needs to be directly accessible. Authors can
only rely on this technique to satisfy the success criterion if they are not relying
on the direct accessibility of the media's technology in their conformance claim,
and reasonably expect users will be able to access the fallback.
Example 1: An object includes a long description that describes it
<object classid="http://www.example.com/analogclock.py"> <p>Here is some text that describes the object and its operation.</p> </object>
Example 2: An object includes non-text content with a text alternative
<object classid="http://www.example.com/animatedlogo.py"> <img src="staticlogo.gif" alt="Company Name" /> </object>
Example 3: The image object has content that provides a brief description of the function of the image
<object data="companylogo.gif" type="image/gif"> <p>Company Name</p> </object>
This example takes advantage of the fact the
object elements may be nested
to provide for alternative representations of information.
<object classid="java:Press.class" width="500" height="500"> <object data="Pressure.mpeg" type="video/mpeg"> <object data="Pressure.gif" type="image/gif"> As temperature increases, the molecules in the balloon... </object> </object> </object>

- Check that the body of each
objectelement contains a text alternative for the object.
- #1 is true.
