HTML entity for Star Operator (U+22C6) — named, hex, decimal, and CSS tutorial

What You'll Learn

How to display Star Operator (⋆) in HTML using named, hexadecimal, decimal, and CSS escape methods. This character is U+22C6 (STAR OPERATOR) in the Mathematical Operators block (U+2200–U+22FF)—a binary operator used in algebra, convolution, and related mathematical notation.

Render it with ⋆, ⋆, ⋆, or CSS \22C6. Do not confuse ⋆ with decorative Black Star ★ (U+2605, ★) or Star Equals ≛ (U+225B).

🧠 How It Works

1

Named HTML Entity

&Star; is the semantic named entity for the star operator—the most readable option in source HTML.

HTML markup
2

Hexadecimal Code

&#x22C6; references code point U+22C6 using hex digits 22C6.

HTML markup
3

Decimal HTML Code

&#8902; is the decimal equivalent (8902) for the same character.

HTML markup
4

CSS Entity

\22C6 is the CSS escape for U+22C6, used in the content property of pseudo-elements.

CSS stylesheet
=

Same visual result

All four methods produce ⋆. Unicode U+22C6 in Mathematical Operators (U+2200–U+22FF).

✅

Use Cases

Star Operator (⋆) commonly appears in:

📊 Math expressions

Equations and formulas using star operations in algebra.

🏫 Academic papers

Research articles, proofs, and scholarly mathematical content.

📚 Educational sites

Online courses, textbooks, and tutorials teaching algebra.

🔬 Scientific docs

Technical documentation for convolution and operator notation.

💻 Math software UI

Calculator interfaces and computational tool labels.

📖 Reference guides

Symbol tables and operator cheat sheets for developers.

💡 Best Practices

Do

  • Prefer &Star; for readable HTML source code
  • Use &#x22C6; or &#8902; when named entities are unavailable
  • Provide context or alt text for screen readers in mathematical content
  • Use math-friendly fonts that support Mathematical Operators
  • Pick one reference style and stay consistent per project

Don’t

  • Use padded Unicode notation like U+022C6—the correct value is U+22C6
  • Use CSS \022C6 with a leading zero—prefer \22C6
  • Confuse ⋆ with Black Star ★ (U+2605) or Star Equals ≛ (U+225B)
  • Use lowercase &star; (white star U+2606) when you mean the math operator
  • Put CSS escape \22C6 in HTML text nodes

❓ Frequently Asked Questions

Use &Star; (named), &#x22C6; (hex), &#8902; (decimal), or \22C6 in CSS content. All four render ⋆.
U+22C6 (STAR OPERATOR). Mathematical Operators (U+2200–U+22FF). Hex 22C6, decimal 8902, named entity &Star;.
No. ⋆ (U+22C6) is STAR OPERATOR in Mathematical Operators. ★ (U+2605) is BLACK STAR in Miscellaneous Symbols with entity &starf;. They look similar but serve different purposes.
For mathematical expressions, algebraic notation, academic papers, scientific documentation, educational materials, and research content involving star operations such as convolution or specialized binary operators.
⋆ denotes a star operation in algebra—commonly used for convolution, the Hodge star operator, or other context-specific binary operations defined in mathematical notation.
