HTML Deprecated Tags: <acronym>, <center>, aur <marquee>

Deprecated Tags Kya Hote Hain?

HTML me, "deprecated" tags woh hote hain jo ab HTML standards (jaise HTML5) ka hissa nahi hain aur unka use karna recommend nahi kiya jaata. Inki jagah modern, semantic alternatives aa gaye hain. In tags ka use karne se aapki website aage chalkar browsers me ajeeb tarah se dikh sakti hai.

1. The <acronym> Tag

<acronym> tag ka use acronyms (jaise 'HTML', 'CSS') ko define karne ke liye hota tha.

Modern Alternative: <abbr>

HTML5 me, <acronym> ko <abbr> (abbreviation) tag se replace kar diya gaya hai. Ab sabhi abbreviations aur acronyms ke liye <abbr> tag ka use karna chahiye.

<p>I love <abbr title="HyperText Markup Language">HTML</abbr>.</p>

2. The <center> Tag

<center> tag ka use content ko horizontally center align karne ke liye hota tha.

Modern Alternative: CSS text-align

Yeh ek presentational tag tha. Modern web development me styling ke liye hamesha CSS ka use karna chahiye. Content ko center karne ke liye aap CSS ki text-align: center; property ka use kar sakte hain.

<div style="text-align: center;">
  <p>This content is centered.</p>
</div>

3. The <marquee> Tag

<marquee> tag ka use text ya image ko horizontally ya vertically scroll karne ke liye hota tha.

Modern Alternative: CSS Animations

Marquee tag bohot distracting tha aur iska use user experience ko kharab karta tha. Agar aapko aisi functionality chahiye, toh CSS animations ka use karna ek behtar aur more controllable tarika hai.

/* CSS Animation Example for Scrolling Text */
@keyframes marquee {
  0%   { transform: translateX(100%); }
  100% { transform: translateX(-100%); }
}
.scrolling-text {
  white-space: nowrap;
  overflow: hidden;
  animation: marquee 10s linear infinite;
}

• Styling ke liye hamesha CSS ka use karein, na ki HTML tags ka (jaise <center>).
• <acronym> ki jagah <abbr> use hota hai.
• <marquee> jaise effects ke liye CSS animations ka use karein.
