HTML Obsolete Tags

Obsolete (or disapproved) tags are HTML key point that were formerly part of earlier HTML performances but are no longer supported or recommended in futuristic HTML (especially HTML5).

These tags may still work in some browsers, but their operation is discouraged because better and further semantic option are available.

Common Obsolete tags in HTML

• <font> – Adapted to define font face, size, and color. Use CSS font-family, font-size, and color properties instead.
• <center> – Adapted to center-align content. Use CSS text-align: center; instead.
• <big> – Made text appear larger than normal. Use CSS font-size property instead.
• <strike> – Created strikethrough text. Use <del> or CSS text-decoration: line-through; instead.
• <u> – Underscored text without meaning. Use CSS text-decoration: underline; or <ins> if the text has semantic meaning (inserted text).
• <applet> – Added Java applets. Deprecated due to security pitfalls. Use <object> or other modern technologies instead.
• <acronym> – Defined acronyms. Use <abbr> instead.
• <frameset>, <frame> – For making framed layouts. No longer supported in HTML5. Use <iframe> for embedded content or modern layouts like Flexbox and Grid.

        </font>
         <center><u>Welcome
         </u></center>
