Why the blink tag doesn't work

Answer 1

The <blink> value is valid but is deprecated and most browsers ignore it.

Answer 2

It was deprecated a long time ago, it isn't valid HTML. Same as `<marquee>`. It doesn't exist as part of HTML. At this point in time, you might as well ask why the `<cheese>` tag doesn't work; it doesn't work because it doesn't exist.

Answer 3

tanks you all
and I would like to know if that exist an great application that runs php and html offline ? ?

Answer 4

All dynamic page rendering (eg, text scrolling and blinking) should be implemented via Javascript, not HTML tags. HTML alone is supposed to be completely static, and that's the direction the HTML standard is heading in.
