Explanation of text boxes, watermarks and flashing objects

Text boxes and watermarks

Screen readers and other assistive technology cannot access information in text boxes or watermarks. Therefore, vital information (such as Respond by X Date, CONFIDENTIAL, or Do Not Distribute) must also be duplicated at or near the start of the main content area.

Flashing objects

Unless there’s a compelling business need, flashing objects should be excluded. If you feel you do have a compelling business need, ensure your object flashes below 3Hz.
