What You'll Learn

How to display the questioned equal to symbol (≟) in HTML using hexadecimal, decimal, named entity, and CSS escape methods. This is an equals sign with a question mark above it, used in mathematics to express equality that is questioned or uncertain.

It is U+225F (QUESTIONED EQUAL TO) in the Mathematical Operators block (U+2200–U+22FF). Use ≟, ≟, the named entity ≟, or CSS \225F. Do not confuse ≟ with ? (question mark ?).

Complete HTML Example

A simple example showing ≟ using hexadecimal code, decimal HTML code, the named entity, and a CSS content escape:

html
<!DOCTYPE html>
<html>
<head>
 <style>
  #point::after{
   content: "\225F";
  }
 </style>
</head>
<body>
<p>Hex: &#x225F;</p>
<p>Decimal: &#8799;</p>
<p>Named: &equest;</p>
<p>CSS: <span id="point"></span></p>
</body>
</html>

See ≟ rendered live in different contexts:

Glyph ≟
Math example a ≟ b (questioned equality)
Compare = equal   ≟ questioned   ≠ not equal
Named entity &equest; ≠ &quest;
Numeric refs &#x225F; &#8799; \225F

🧠 How It Works

1

Hexadecimal Code

&#x225F; uses the Unicode hexadecimal value 225F to display the questioned equal to symbol.

HTML markup
2

Decimal HTML Code

&#8799; uses the decimal Unicode value 8799 to display the same character.

HTML markup
3

CSS Entity

\225F is used in CSS stylesheets in the content property of pseudo-elements like ::before and ::after.

CSS stylesheet
4

Named Entity

&equest; is the semantic named entity for ≟—note the spelling differs from &quest; (question mark).

HTML markup
=

Same visual result

All four methods produce: ≟. Unicode U+225F in Mathematical Operators (U+2200–U+22FF).

Use Cases

The questioned equal to symbol (≟) commonly appears in:

📚 Math Notation

Expressing equality that is uncertain or under question.

🔬 Logic

Formal logic and proof sketches with tentative relations.

🎓 STEM Education

Textbooks and online courses teaching advanced symbols.

💻 MathML / LaTeX Docs

Web references comparing HTML entities to TeX symbols.

📋 Unicode References

Character tables and Mathematical Operators documentation.

📝 Research Papers

HTML versions of papers using questioned equality notation.

♿ Accessibility

Pair ≟ with “questioned equal to” in alt text or nearby prose.

💡 Best Practices

Do

  • Use &equest; for readable math markup
  • Distinguish &equest; (≟) from &quest; (?)
  • Use math fonts when professional notation is required
  • Pick one style (named, hex, or decimal) per project
  • Test rendering across browsers and devices

Don’t

  • Type &quest; when you mean ≟—that renders ?
  • Substitute = or ≠ when ≟ is intended
  • Use CSS escape \225F inside HTML text nodes
  • Assume every font includes U+225F—test STEM content
  • Use HTML entities in JS (use \u225F instead)

Key Takeaways

1

Three HTML references plus a named entity render ≟

&#x225F; &#8799; &equest;
2

For CSS stylesheets, use the escape in the content property

\225F
3

Unicode U+225F is QUESTIONED EQUAL TO in Mathematical Operators

4

&equest; is the named entity—not &quest;

❓ Frequently Asked Questions

Use &#x225F; (hex), &#8799; (decimal), &equest; (named entity), or \225F in CSS content. All produce ≟.
U+225F (QUESTIONED EQUAL TO). Mathematical Operators block. Hex 225F, decimal 8799.
&equest; is the named HTML entity for ≟. Do not confuse it with &quest;, which renders the question mark (?).
It denotes equality that is questioned or uncertain—an equals sign with a question mark above, used when a relation may hold but is not certain.
In math papers, logic notation, STEM education, and documentation where you need to express questionable or tentative equality.
