Why Is the Tag Deprecated?

The tag has been deprecated due to concerns about accessibility, user experience, and performance. It has several issues that render it unsuitable for modern web design.

Accessibility: The tag can be inaccessible to users with certain impairments, such as those with attention deficit hyperactivity disorder (ADHD) or motion sickness. The constant movement of the text can make it difficult to focus and read.

User Experience: The tag often leads to a poor user experience. The scrolling text can be distracting and disruptive, especially in crowded or busy environments. It can also create compatibility issues across different browsers and devices.

Performance: The tag can impact page performance by consuming significant CPU resources. The constant processing required to keep the text scrolling can slow down websites, especially on mobile devices.

The Best Alternative

The most effective replacement for the tag is CSS3 animations. CSS animations offer a much more flexible and accessible solution for scrolling text. Here's an example of a CSS animation that mimics the functionality of the tag:

.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); }
}

This example will create a scrolling text effect that is both accessible and performant. Additionally, CSS animations can be easily customized to achieve the desired effect, including creating a bottom-to-top scrolling effect.
