To create blinking text using HTML, the <blink> tag was traditionally used, as in <blink>annoying text</blink>. However, many modern browsers have deprecated this tag due to its disruptive nature, leading to inconsistent behavior. In a forum setting where HTML is permitted, users have reported that even using the <blink> tag within a complete HTML structure does not produce the desired blinking effect. This may be due to the forum disabling the blink feature or browser compatibility issues. Overall, the <blink> tag is no longer a reliable method for achieving blinking text in contemporary web development.
