HTML Tags You Should Stop Using in 2026 (And What to Use Instead)

If you’re still using outdated markup, it’s time to update your code. There are several HTML tags you should stop using in 2026 — not because they don’t work, but because they’re deprecated, non-semantic, or harmful to accessibility and SEO.

I still remember reviewing a beginner’s project where the layout was built using <table>, text styling was done with <font>, and alignment relied on <center> tag. It worked in the browser. But under the hood? It was outdated, inaccessible, and hard to maintain.

In 2026, writing modern HTML means writing semantic, accessible, and future-proof code.

In this guide, I’ll show you:

• HTML tags you should stop using
• Tags that are technically valid but misused
• Modern alternatives you should use instead
• Why updating your HTML improves SEO and performance

Let’s clean up your markup.

1. <font> — Stop Styling Text in HTML

❌ Why You Should Stop

The <font> tag was used to control:

• Font size
• Font color
• Font face

Example (old way):

This tag is deprecated and removed in HTML5.

✅ What to Use Instead

Use CSS:

🚀 Why This Matters

• Cleaner separation of structure and style
• Better maintainability
• Improved SEO readability
• Easier theming and responsiveness

2. <center> — Alignment Belongs in CSS

❌ The Problem

The <center> tag was used like this:

It’s obsolete in modern HTML.

✅ Modern Alternative

Use CSS:

Or with Flexbox:

Modern layout belongs in CSS — not HTML structure.

3. <marquee> — Please Don’t Do This in 2026

Yes, it still works in some browsers. But, no, you shouldn’t use it.

XHTML

<marquee>Breaking News</marquee>

1	<marquee>Breaking News</marquee>

❌ Why It’s Bad

• Not part of any official HTML standard
• Poor accessibility
• Unprofessional appearance
• Limited customization

✅ Use CSS Animations Instead

CSS gives you full control and better performance.

4. <b> and <i> — Often Misused

This one surprises beginners.

These tags are not deprecated — but they’re often misused.

❌ Common Mistake

Using <b> to make something important.

✅ Better Alternative

Use semantic tags:

and

Why It Matters

• Screen readers understand <strong> and <em>
• Improves accessibility
• Adds semantic meaning for search engines

5. <table> for Layout — A Big No

Back in the early web days, developers used tables to create layouts.

❌ Why This Is Outdated

• Not responsive
• Hard to maintain
• Bad for accessibility
• Poor semantic structure

✅ Use CSS Grid or Flexbox

Modern layout tools:

• Flexbox
• CSS Grid

These are powerful, clean, and responsive by design.

6. <big> and <strike>

These are obsolete.

Instead of:

Use:

The <del> tag is semantic and useful for SEO when showing price changes. For large text, use class (e.g. .large-text) and apply font-size CSS.

Why Removing These Tags Improves SEO

Search engines prefer:

• Semantic HTML
• Clean structure
• Accessibility-friendly markup
• Modern standards

When your HTML is semantic:

• Crawlers understand hierarchy better
• Screen readers interpret content properly
• Page performance improves
• Maintainability increases

That’s a ranking advantage over messy legacy code.

Quick Summary

❌ Stop using:

• <font>
• <center>
• <marquee>
• <big>
• <strike>
• <table> for layout

⚠️ Use carefully:

• <b>
• <i>

✅ Use instead:

• CSS for styling
• Semantic tags like <strong>, <em>, <del>
• Flexbox & Grid for layout

Final Thoughts

HTML looks simple — but writing modern HTML is about meaning, not just making things “look right.”

In 2026, developers who understand semantic structure will build:

• More accessible websites
• Better ranking pages
• Cleaner codebases
• Future-proof projects

Even though some deprecated HTML tags still render in modern browsers, relying on them in 2026 signals outdated development practices.

If your HTML still contains outdated tags, now is the time to clean it up.
