Object with no fallback content Accessibility Checkpoint


object elements should contain fallback content.


Place fallback content inside the object element, which is displayed when objects are disabled or unsupported (e.g. when Flash and plugins are displayed on mobile devices). For example: <object>Alternative text content</object>
