HTML Entity for Clockwise Contour Integral (∲)
What You'll Learn
How to display the Clockwise Contour Integral (∲) in HTML and CSS. This character is U+2232 (CLOCKWISE CONTOUR INTEGRAL) in the Mathematical Operators block (U+2200–U+22FF). It denotes integration around a closed contour in the clockwise direction—common in complex analysis and physics.
There is no named HTML entity for U+2232. Use ∲ or ∲ in markup, or \2232 in stylesheet content. Do not confuse ∲ with Contour Integral U+222E (∮, ∮) or Anticlockwise Contour Integral U+2233 (∳).

🧠 How It Works
Hexadecimal Code
∲ references code point U+2232 using hex digits 2232.
Decimal HTML Code
∲ is the decimal equivalent (8754) for the same character.
CSS Entity
\2232 is the CSS escape for U+2232, used in the content property of ::before or ::after.
Same visual result
All three methods produce the Clockwise Contour Integral glyph: ∲. Unicode U+2232 sits in Mathematical Operators (U+2200–U+22FF). No named HTML entity exists.
Use Cases
The Clockwise Contour Integral (∲) commonly appears in:
Contour and line integrals in advanced calculus notation.
Integration around closed paths in the complex plane.
Electromagnetism, field theory, and engineering formulae.
Published research, textbooks, and lecture notes.
Equation editors and formula displays alongside MathML or KaTeX.
Unicode tables and mathematical operator glossaries.
Use MathML or aria-label="clockwise contour integral" for screen readers.
💡 Best Practices
Do
- Use math fonts (Cambria Math, STIX Two Math, serif) for clear integral glyphs
- Prefer
∲or∲consistently in HTML - Consider MathML or KaTeX for complex multi-line equations
- Distinguish clockwise (U+2232) from anticlockwise (U+2233) notation
- Use
\2232only inside CSScontent, not in HTML text nodes
Don’t
- Confuse U+2232 (∲) with U+2233 anticlockwise (∳) or U+222E contour (∮)
- Use U+02232 notation—the correct code point is U+2232
- Assume every font renders Mathematical Operators identically
- Expect a named HTML entity for U+2232—none exists
- Mix hex and decimal styles randomly in one file
Key Takeaways
