This is a physical style element that makes contained text within
blink on and off on the screen. Netscape created the element and is currently
the only major browser or standard to support it.
Many readers find the use of this element to be particularly annoying,
and indeed it is distracting to have text disappear from the screen.
If the user is not presently reading a blinking passage (when the blinking
occurs outside of the focus of the field of vision) it can distract a reader's
attention and it may take several moments for the user to identify what passage
is changing.
Seriously evaluate the need for using this element, as it can create
as many problems as it solves, and only one browser type will display
its effects.
Browser Peculiarities
DTD Note: Internet Explorer 4.0 now recognizes
this element only so far as common attributes are concerned - BLINK does
not actually produce a blinking content effect in IE, but style sheet
attributes and event handlers can be successfully applied.
All platforms and many of the versions of Netscape have the ability to
toggle the BLINK functionality on or off. This control is not exposed
in the main user interface. See Mosh Teitelbaum's
"Disabling Blinking Text" page for more details.
