HTML Entity for NOR (⊽)
What You'll Learn
How to display the NOR symbol (⊽) in HTML using named, hexadecimal, decimal, and CSS escape methods. The NOR operator (Peirce arrow / bar vee) represents logical NOR—true only when neither operand is true—and is essential for programming documentation, Boolean algebra, and digital logic content.
This character is U+22BD (NOR) in the Mathematical Operators block (U+2200–U+22FF). Render it with ⊽, ⊽, ⊽, or CSS escape \22BD.

🧠 How It Works
Named Entity
⊽ is the HTML named entity for U+22BD—the most readable choice when writing logic markup.
Hexadecimal Code
⊽ uses the Unicode hexadecimal value 22BD. The x prefix indicates hexadecimal format.
Decimal HTML Code
⊽ uses the decimal Unicode value 8893 to display the same character.
CSS Entity
\22BD is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result
All four methods produce: ⊽. Unicode U+22BD in Mathematical Operators (U+2200–U+22FF).
Use Cases
The NOR symbol (⊽) is commonly used in:
Describe NOR in prose next to code (e.g. A ⊽ B).
Truth tables, lecture notes, and logic simplification examples.
Digital electronics and hardware documentation for NOR gates.
Computer architecture and discrete math course materials.
Unicode charts and HTML entity documentation for logic symbols.
Formal specifications involving functional completeness and NOR logic.
💡 Best Practices
Do
- Use
⊽for readable logic markup - Distinguish NOR (⊽) from NAND (⊼) and XOR (⊻)
- Pair ⊽ with plain-language description on first use
- Use fonts that cover Mathematical Operators (Cambria Math, etc.)
- Serve pages with UTF-8 (
<meta charset="utf-8">)
Don’t
- Confuse ⊽ (
⊽) with ⊼ (NAND) or ⋏ (curly logical or) - Use padded Unicode notation like U+022BD—the correct value is
U+22BD - Put CSS escape
\22BDin HTML text nodes - Use
\022BDin CSS—the correct escape is\22BD - Rely on the glyph alone without accessible description
