HTML Entity for For All (∀)
What You'll Learn
How to display the For All symbol (∀) in HTML using hexadecimal, decimal, named entity, and CSS escape methods. This character is U+2200 (FOR ALL, universal quantifier) in the Mathematical Operators block (U+2200–U+22FF)—read as “for all” in logic and mathematics.
Render it with ∀, ∀, the named entity ∀, or CSS escape \2200. Do not confuse ∀ with exists (∃, ∃) or the letter A.

This example demonstrates the For All symbol (∀) using hexadecimal code, decimal HTML code, the named entity, and a CSS content escape:
<!DOCTYPE html>
<html>
<head>
<style>
#point:after{
content: "\2200";
}
</style>
</head>
<body>
<p>For All using Hexadecimal: ∀</p>
<p>For All using HTML Code: ∀</p>
<p>For All using HTML Entity: ∀</p>
<p id="point">For All using CSS Entity: </p>
</body>

Hexadecimal Code
∀ uses the Unicode hexadecimal value 2200 to display the For All symbol. The x prefix indicates hexadecimal format.
Decimal HTML Code
∀ uses the decimal Unicode value 8704 to display the same character.
Named Entity
∀ is the semantic named entity for the universal quantifier—often preferred in readable math and logic markup.
CSS Entity
\2200 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result
All four methods produce the glyph: ∀. Unicode U+2200 in the Mathematical Operators block (U+2200–U+22FF).
Use Cases
The For All symbol (∀) is commonly used in:
Formulas, equations, and notation with universal quantification.
Formal logic, predicate calculus, and statements like “for all x, P(x)”.
Mathematics, philosophy, and computer science publications.
Online courses, tutorials, and learning materials for math and logic.
Formal methods, verification, and logic in CS documentation.
HTML entity lists, Unicode charts, and character references.
💡 Best Practices
Do
- Use
∀for readable universal quantifier markup - Use
∃(∃) when “there exists” is meant - Use math-friendly fonts (e.g. Cambria Math) for clear ∀ rendering
- Serve pages with UTF-8 (
<meta charset="utf-8">) - Consider MathML or
aria-labelfor complex math accessibility
Don’t
- Confuse ∀ (
∀) with ∃ (∃, there exists) - Substitute the letter
Afor the quantifier symbol - Put CSS escape
\2200in HTML text nodes - Mix entity styles randomly in one file
- Assume every font distinguishes ∀ and ∃ clearly
