HTML entity for normal subgroup of symbol (U+22B3) — named vrtri, hex, decimal, and CSS tutorial

What You'll Learn

How to display the normal subgroup of symbol (⊳) in HTML using named, hexadecimal, decimal, and CSS escape methods. This glyph is the paired operator to ⊲ and is used in group theory and abstract algebra to express normal-subgroup-of relationships.

This character is U+22B3 (NORMAL SUBGROUP OF) in the Mathematical Operators block (U+2200–U+22FF). Render it with ⊳, ⊳, ⊳, or CSS escape \22B3.

Complete HTML Example

This example demonstrates the normal subgroup of symbol (⊳) using hexadecimal code, decimal HTML code, the named entity, and a CSS content escape:

html
<!DOCTYPE html>
<html>
<head>
 <style>
  #point::after{
   content: "\22B3";
  }
 </style>
</head>
<body>
<p>Normal Subgroup Of using Hexadecimal: &#x22B3;</p>
<p>Normal Subgroup Of using HTML Code: &#8883;</p>
<p>Normal Subgroup Of using Named Entity: &vrtri;</p>
<p id="point">Normal Subgroup Of using CSS Entity: </p>
</body>
</html>

🧠 How It Works

1

Named Entity

&vrtri; is the HTML named entity for U+22B3—the most readable choice when writing group-theory markup.

HTML markup
2

Hexadecimal Code

&#x22B3; uses the Unicode hexadecimal value 22B3. The x prefix indicates hexadecimal format.

HTML markup
3

Decimal HTML Code

&#8883; uses the decimal Unicode value 8883 to display the same character.

4

CSS Entity

\22B3 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

CSS stylesheet
=

Same visual result

All four methods produce: ⊳. Unicode U+22B3 in Mathematical Operators (U+2200–U+22FF).

✅

Use Cases

The normal subgroup of symbol (⊳) is commonly used in:

📐 Group theory

Express that H is a normal subgroup of G using ⊳ notation.

🎓 Academic texts

Textbooks, lecture notes, and course materials on abstract algebra.

📄 Research papers

Formal definitions, theorems, and proofs involving quotient groups.

💻 Math wikis

Online references and encyclopedia articles on subgroup structure.

📊 Reference guides

Unicode charts and HTML entity documentation for math symbols.

📝 Technical writing

Specifications and documentation for mathematical software libraries.

💡 Best Practices

Do

  • Use &vrtri; for readable group-theory markup
  • Distinguish ⊳ (normal subgroup of) from ⊲ (normal subgroup)
  • Pair ⊳ with plain-language description on first use
  • Use fonts that cover Mathematical Operators (Cambria Math, STIX, etc.)
  • Serve pages with UTF-8 (<meta charset="utf-8">)

Don’t

  • Confuse ⊳ (&vrtri;) with ⊲ (&vltri;)—they are different symbols
  • Use padded Unicode notation like U+022B3—the correct value is U+22B3
  • Put CSS escape \22B3 in HTML text nodes
  • Use \022B3 in CSS—the correct escape is \22B3
  • Rely on the glyph alone without accessible description

Key Takeaways

1

Three HTML references plus CSS all render ⊳

&#x22B3; &#8883; &vrtri;
2

For CSS stylesheets, use the escape in the content property
