Why is the `` tag deprecated, and what's the best alternative for creating scrolling text?

Why is Deprecated: Understanding the Controversy

The tag, once a popular HTML element used to create scrolling text animations, has fallen into disuse due to accessibility concerns and browser inconsistencies. Its deprecation signifies a shift towards more modern and efficient web design practices.

Accessibility Issues:

Scrolling text, as generated by , can be difficult for users with cognitive disabilities, seizure disorders, or vestibular disorders. The continuous movement can trigger disorientation, nausea, and migraines. Additionally, text within a may be difficult for screen readers to parse, creating accessibility barriers for visually impaired users.

Browser Incompatibilities and Standardization Failures:

has faced inconsistent support across browsers, with some older browsers ceasing to render it. This variability in behavior made it challenging for developers to ensure consistent functionality. Furthermore, despite efforts to standardize CSS properties like "marquee-play-count" and "marquee-speed," they were eventually removed from the specification, leaving no robust CSS alternatives for creating scrolling text.

What is the Easiest Substitution for :

Although remains deprecated, modern CSS3 animations offer a powerful and accessible solution for creating text movement effects. Using CSS3, developers can achieve a similar scrolling effect with smoother, more customizable animations that are compatible across major browsers.

The following code snippet provides an example of a simple CSS3 animation that scrolls text horizontally:

.marquee {
  width: 450px;
  line-height: 50px;
  background-color: red;
  color: white;
  white-space: nowrap;
  overflow: hidden;
  box-sizing: border-box;
}

.marquee p {
  display: inline-block;
  padding-left: 100%;
  animation: marquee 15s linear infinite;
}

@keyframes marquee {
  0%   { transform: translate(0, 0); }
  100% { transform: translate(-100%, 0); }
}
Copy after login

By leveraging CSS3 animations, developers can create a scrolling text effect that is visually appealing, accessible, and compatible across major browsers, eliminating the need for the deprecated tag.
