HTML Entity for Does Not Precede Or Equal (⋠)
What You'll Learn
How to display the Does Not Precede Or Equal symbol (⋠) in HTML using named, hexadecimal, decimal, and CSS entity methods. This character is U+22E0 (DOES NOT PRECEDE OR EQUAL) in the Mathematical Operators block (U+2200–U+22FF) and denotes that one element does not precede or equal another in a partial order—the negation of “precedes or equal” (≼, ≼).
Render it with the named entity ⋠, ⋠, ⋠, or CSS escape \22E0 in the content property. Do not confuse with ⪯̸ (does not precede, U+2280) or ∤ (does not divide, U+2224).

<style>
#point:after{
content: "\22E0";

🧠 How It Works
Named Entity
⋠ is the HTML named entity for Does Not Precede Or Equal — the negation of ≼ (precedes or equal, ≼).
Hexadecimal Code
⋠ uses the Unicode hexadecimal value 22E0. The x prefix indicates hexadecimal format.
Decimal HTML Code
⋠ uses the decimal Unicode value 8928 to display the same character.
CSS Entity
\22E0 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+22E0 is the does-not-precede-or-equal relation. For precedes or equal (≼), use ≼.
Use Cases
The symbol (⋠) commonly appears in the following scenarios:
When a ⋠ b means a does not precede or equal b in a partial order.
Posets and lattices where ≼ and ⋠ denote precedes-or-equal and its negation.
Discrete math courses teaching partial orders and relation symbols.
Web pages rendering mathematical notation with proper Unicode relations.
Entity references for order-theoretic symbols in HTML.
HTML entity references for education and research.
💡 Best Practices
Do
- Use
⋠for readable HTML source - Pair with
≼(≼) when teaching precedes-or-equal pairs - Use fonts that cover Mathematical Operators (U+2200–U+22FF)
- Pair with text or ARIA (“does not precede or equal”)
- Pick one entity style per project for consistency
Don’t
- Confuse
⋠with⪯̸(does not precede) or∤ - Swap
⋠and≼(different relations) - Use CSS escape
\22E0inside HTML markup - Mix hex, decimal, and named styles randomly in one file
- Rely on the symbol alone without accessible description
