The tag was never an official standard, and is now completely abandoned by all browsers.
Is there a standards compliant way of making text blink?
You could take advantage of JavaScript's setInterval function:
setInterval
const spanEl = document.querySelector('#spanEl'); var interval = setInterval(function() { spanEl.style.visibility = spanEl.style.visibility === "hidden" ? 'visible' : 'hidden'; }, 250);
This text will blink!
