Blink element is deprecated

How to replace the blink element?

The <blink> element is deprecated and no longer supported by browsers. Replace it with an alternative that conveys the same emphasis without blinking:

<p>Start free trial. <blink>It is free!</blink></p>

<p>Start free trial. <strong>It is free!</strong></p>

<style>
  @media (prefers-reduced-motion: no-preference) {
    .highlight { animation: fade 1s ease-in-out infinite alternate; }
  }
  @keyframes fade { from { opacity: 1; } to { opacity: 0.4; } }
</style>
<p>Start free trial. <span class="highlight">It is free!</span></p>

Why is this important?

Blinking text is distracting and harmful — especially for users with cognitive disabilities or attention disorders. The <blink> element is also deprecated and unsupported in all modern browsers, so it will not work at all.

If you need to draw attention to content, use semantic elements (<strong>, <em>) or CSS with a prefers-reduced-motion media query. This respects the operating system’s “reduce motion” setting — important for people who have vestibular disorders, as on-screen animation can cause dizziness, nausea, or disorientation.
