HTML tags that no longer work stay in the deprecated list. This article explains them and shows the modern replacements.
Meaning of HTML Deprecated Tags
A deprecated tag is an old element that no longer has full browser support. Developers must avoid it because standards no longer accept it. HTML5 offers new tags that replace each old one with more stable options.
Here is a list that shows you some of them:
<center><font><big><strike><acronym><applet><u>
Tags are no longer used once better elements or CSS rules replace them. Standards remove them to stop conflicts.
Some browsers still read these tags, but new versions stop full support. Code that uses them may not work in future releases or may work with errors.
Here are alternatives to deprecated tags:
- Use CSS
text-aligninstead of<center>. - Use CSS
font-familyandfont-sizeinstead of<font>. - Use
<strong>or<em>instead of<b>or<i>. - Use
<del>instead of<strike>. - Use
<abbr>instead of<acronym>. - Use
<canvas>instead of<applet>.
So, how do deprecated tags affect SEO?
Old tags make HTML weak and confuse search engines and assistive tools. Screen readers might skip or read the content wrong.
The clean HTML5 tags show the structure in a way both browsers and machines understand.
Examples of HTML Deprecated Tags and Alternatives
Replace <center> with CSS:
<p style="text-align:center;">This text is at the center</p>This example shows how CSS style controls text position in place of the <center> tag.
Replace <font> with CSS:
<p style="font-family:Arial; font-size:18px;">Hello World</p>This example shows how inline CSS handles text design and removes the need for the old <font> tag.
Replace <strike> with <del>:
<p>Old price: <del>$100</del> New price: $80</p>This example shows how <del> marks removed content in place of <strike> which no longer has support.
Replace <applet> with <canvas>:
<canvas id="box" width="200" height="100"></canvas>
<script>
let box=document.getElementById("box").getContext("2d");
box.fillStyle="blue";
box.fillRect(20,20,150,60);
</script>This example shows how <canvas> draws graphics in modern HTML and fully replaces the <applet> element.
