Moving, scrolling and blinking content creates a sense of motion on the web page. Animations, real time games, motion pictures are few examples.
A scrolling feature may make it difficult for a low vision user to read the content. It may also be difficult for a screen reader. Content that blinks for more than 5 seconds causes distraction for users who have attention deficit disorders making it difficult to concentrate on the rest of the content.
