HTML Entity for Does Not Succeed (⊁)
What You'll Learn
How to display the Does Not Succeed symbol (⊁) in HTML using named, hexadecimal, decimal, and CSS entity methods. This character is U+2281 (DOES NOT SUCCEED) in the Mathematical Operators block (U+2200–U+22FF) and denotes that one element does not succeed another in an order—the negation of “succeeds” (≿, &Succ;).
Render it with the named entity ⊁, ⊁, ⊁, or CSS escape \2281 in the content property. Do not confuse with ⪯̸ (does not precede, U+2280), superset ⊃ (⊃), or ∤ (does not divide, U+2224).

This example demonstrates the symbol (⊁) using hexadecimal code, decimal HTML code, the named entity, and a CSS content escape on a pseudo-element:
<!DOCTYPE html>
<html>
<head>
<style>
#point:after{
content: "\2281";
}

🧠 How It Works
Named Entity
⊁ is the HTML named entity for Does Not Succeed — the negation of &Succ; (succeeds, ≿).
Hexadecimal Code
⊁ uses the Unicode hexadecimal value 2281. The x prefix indicates hexadecimal format.
Decimal HTML Code
⊁ uses the decimal Unicode value 8833 to display the same character.
CSS Entity
\2281 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+2281 is the does-not-succeed relation. For succeeds (≿), use &Succ;.
Use Cases
The symbol (⊁) commonly appears in the following scenarios:
When a ⊁ b means a does not succeed b in an order.
Ordered sets and relations where ≿ and ⊁ denote succeeds and its negation.
Discrete math courses teaching succeeds and does-not-succeed symbols.
Web pages rendering mathematical notation with proper Unicode relations.
Entity references for order and relation symbols in HTML.
HTML entity references for education and research.
💡 Best Practices
Do
- Use
⊁for readable HTML source - Pair with
&Succ;(≿) when teaching succeeds pairs - Use fonts that cover Mathematical Operators (U+2200–U+22FF)
- Pair with text or ARIA (“does not succeed”)
- Pick one entity style per project for consistency
Don’t
- Confuse
⊁with⪯̸(does not precede) or⊃(superset) - Swap
⊁and&Succ;(different relations) - Use CSS escape
\2281inside HTML markup - Mix hex, decimal, and named styles randomly in one file
- Rely on the symbol alone without accessible description

❓ Frequently Asked Questions
⊁ (named), ⊁ (hex), ⊁ (decimal), or \2281 in CSS content. All produce ⊁.U+2281 (hex 2281, decimal 8833) in the Mathematical Operators block. It means “does not succeed” (negation of ≿).U+2281, ⊁) means does not succeed. ≿ (U+227F, &Succ;) means succeeds. They are negations of each other.⊁ is U+2281 (does not succeed). &Succ; is U+227F (succeeds). ∤ is U+2224 (does not divide). Each entity maps to a different symbol.Explore More HTML Entities!
