This is an experimental implementation of potential future techniques that may not yet be supported by web standards.

• This example may include ARIA, HTML, CSS, or other code that is not yet included in a final web standard specification.
• Experimental content is published in the APG only to facilitate discussion, gather feedback, and support testing of new features in browsers and assistive technologies.
• There may be little or no support for this example in any or most browser and assistive technology combinations.
• The ARIA and Assistive Technologies Project is developing measurements of assistive technology support for APG examples.
