About Crop Circles. Screen readers ignore all bit-map text. If you do use bit-map text, provide ALT text for it. Some people with cognitive limitations or visual disabilities are unable to read moving text quickly enough or at all. Movement can also cause such a distraction that the rest of the page becomes unreadable for people with cognitive disabilities.
Screen readers are unable to read moving text.
People with physical disabilities might not be able to move quickly or accurately enough to interact with moving objects. Use proportional font markups rather than specifying font size. This allows the site to be shown using the user's preferences. Return to Top of Page. For example, a simple decorative graphic may warrant only Alt text.
