What You'll Learn

How to display the Models symbol (⊧) in HTML using named, hexadecimal, decimal, and CSS escape methods. This character is U+22A7 (MODELS) in the Mathematical Operators block (U+2200–U+22FF)—a turnstile-style relation used in model theory and logic to mean “satisfies” or “models,” for example “M ⊧ φ” (structure M models formula φ).

Render it with the named entity ⊧, ⊧, ⊧, or CSS escape \22A7. This is a mathematical logic symbol—not related to 3D graphics or data models. Do not confuse ⊧ with Forces (⊩, ⊩) or the right tack / proves symbol (⊢, ⊢).

Complete HTML Example

This example demonstrates the Models symbol (⊧) using hexadecimal code, decimal HTML code, the named entity, and a CSS content escape:

html
<!DOCTYPE html>
<html>
<head>
 <style>
  #point:after{
   content: "\22A7";
  }
 </style>
</head>
<body>
<p>Models using Hexadecimal: &#x22A7;</p>
<p>Models using HTML Code: &#8871;</p>
<p>Models using Named Entity: &models;</p>
<p id="point">Models using CSS Entity: </p>
</body>
</html>

🧠 How It Works

1

Named Entity

&models; is the HTML named entity for Models—often preferred in readable logic and model-theory markup.

HTML markup
2

Hexadecimal Code

&#x22A7; uses the Unicode hexadecimal value 22A7. The x prefix indicates hexadecimal format.

HTML markup
3

Decimal HTML Code

&#8871; uses the decimal Unicode value 8871 to display the same character.

4

CSS Entity

\22A7 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

CSS stylesheet

Same visual result

All four methods produce: . Unicode U+22A7 in Mathematical Operators. For forcing notation, see Forces (⊩, &Vdash;).

Use Cases

The Models symbol (⊧) is commonly used in:

∧ Model theory

Expressing that a structure satisfies a formula (M ⊧ φ).

🔢 Formal logic

Semantic consequence and satisfaction in first-order logic.

📚 Academia

Logic, philosophy, and computer science textbooks and papers.

💻 CS documentation

Notes on semantics, type systems, and formal verification.

🎓 Education

Online courses and tutorials on logic and discrete mathematics.

🌐 Symbol guides

HTML entity lists, Unicode charts, and character references.

💡 Best Practices

Do

  • Use &models; for readable HTML source in logic notation
  • Distinguish ⊧ (models) from ⊩ (forces) and ⊢ (proves)
  • Use fonts that cover Mathematical Operators (Cambria Math, etc.)
  • Add aria-label (e.g. “models”) for accessibility
  • Serve pages with UTF-8 (<meta charset="utf-8">)

Don’t

  • Confuse this logic symbol with 3D models or MVC data models
  • Confuse &models; with &Vdash; (forces, U+22A9)
  • Put CSS escape \22A7 in HTML text nodes
  • Mix entity styles randomly in one file
  • Rely on the symbol alone without accessible description

Key Takeaways

1

Three HTML references plus CSS all render ⊧

&#x22A7; &#8871; &models;
2

For CSS stylesheets, use the escape in the content property

\22A7
3

Unicode U+22A7 — MODELS (satisfaction)

&models; is the standard named entity

❓ Frequently Asked Questions

Use &models; (named), &#x22A7; (hex), &#8871; (decimal), or \22A7 in CSS content. All produce ⊧.
U+22A7 (MODELS). Mathematical Operators block (U+2200–U+22FF). Hex 22A7, decimal 8871. Denotes satisfaction or “models” in logic.
In model theory, formal logic, and semantics when you need to show that a structure satisfies a formula (e.g. M ⊧ φ). Common in academic papers, textbooks, and CS documentation.
⊧ (U+22A7, &models;) means models or satisfies. ⊩ (U+22A9, &Vdash;) means forces. They are related turnstile symbols used in different logical contexts.
HTML entities (&#8871;, &#x22A7;, or &models;) go directly in markup. The CSS escape \22A7 is used in stylesheets, typically in the content property of pseudo-elements. Same visual result, different layers of the stack.
