What You'll Learn

How to display the All equal to symbol (≌) in HTML using numeric references, the named entity ≌, or a CSS escape. Unicode assigns this code point the official name All equal to (U+224C). In HTML’s named-entity list the same character is called ≌ (“backward congruent”), a mnemonic label—always match the symbol to the definition used in your textbook or style guide.

The character lives in the Mathematical Operators block (U+2200–U+22FF). You may write ≌, ≌, ≌, or \224C in CSS content.

Complete HTML Example

This example shows the All equal to symbol (≌) using hexadecimal code, decimal HTML code, the named entity ≌, and a CSS content escape on a pseudo-element:

html
<!DOCTYPE html>
<html>
<head>
 <style>
  #point:after{
   content: "\224C";
  }
 </style>
</head>
<body>

<p>All Equal To using Hexa Decimal: &#x224C;</p>
<p>All Equal To using HTML Code: &#8780;</p>
<p>All Equal To using HTML Entity: &bcong;</p>
<p id="point">All Equal To using CSS Entity: </p>

</body>
</html>

Named entity In markup, &bcong; expands to the same ≌ as &#x224C;.
Monospace REL-U+224C
Font note Use a math-capable font stack so ≌ aligns cleanly with adjacent operators.

🧠 How It Works

1

Hexadecimal Code

&#x224C; references Unicode 224C in hexadecimal. The x prefix marks a hex numeric character reference.

HTML markup
2

Decimal HTML Code

&#8780; is the decimal code point 8780 for the same character—often used when authors think in decimal Unicode values.

HTML markup
3

Named Entity

&bcong; is the HTML named entity for U+224C (“backward congruent” in entity lists). It keeps hand-written formulas readable.

CSS Entity (Escape)

\224C is the CSS escape (four hex digits) used in content on ::before / ::after to emit ≌ without placing the raw character in HTML.

CSS stylesheet
=

Same visual result

All methods render . Unicode is U+224C (Mathematical Operators, U+2200–U+22FF). Official Unicode name: All equal to. HTML also exposes it as &bcong;.

Use Cases

The All equal to symbol (≌, U+224C) fits these kinds of content:

∑ Algebra & Relations

Equation sheets and blogs where your notation standard specifies this operator between expressions.

📐 Geometry & Proofs

Figure captions and proof steps when ≌ is the chosen congruence-style relation symbol.

📜 Logic & Foundations

Formal notation alongside other Mathematical Operators glyphs.

🎓 STEM Education

Interactive lessons that mirror textbook character sets.

📚 Unicode & Math References

Symbol tables comparing ≌ to ≈, ≅, ≡, and related relations.

💻 Equation Editors & CMS

Fallback HTML when LaTeX or MathML is not available for a single relation sign.

💡 Best Practices

Do

  • Use UTF-8; prefer &bcong; in hand-authored HTML when readability matters
  • Define notation once (tooltip, glossary, or prose) so readers know how you use ≌
  • Pair with math fonts (STIX Two Math, Latin Modern Math, etc.) for consistent operator spacing
  • Use numeric references in generated markup or XML-first pipelines if needed
  • Use \224C only in CSS content, not inside HTML text nodes

Don’t

  • Assume ≌ always means the same as ≅ or ≡ without checking your field’s convention
  • Use ≌ alone as the only explanation of a subtle equivalence for a general audience
  • Mix hex, decimal, and named forms at random in one template without a style guide
  • Paste CSS escapes into HTML markup (they belong in stylesheets)
  • Confuse Unicode’s formal name “All equal to” with every informal spoken label for the glyph

Key Takeaways

1

Three HTML encodings render ≌

&#x224C; &#8780; &bcong;
2

In CSS, use the escape in content on pseudo-elements

❓ Frequently Asked Questions

Use &#x224C; (hex), &#8780; (decimal), &bcong; (named), or \224C in CSS content. All produce ≌.
U+224C (hex 224C, decimal 8780). Unicode’s official name is All equal to; it sits in the Mathematical Operators block (U+2200–U+22FF). HTML lists the named reference &bcong; for the same character.
When your curriculum, paper, or style guide explicitly uses U+224C. If you mean approximate equality or geometric congruence in another sense, your standard may specify ≈, ≅, or ≡ instead.
Markup accepts &#8780;, &#x224C;, or &bcong;. The CSS escape \224C belongs in stylesheets, usually in the content property of ::before or ::after. Same glyph, different layers.
Yes: &bcong; refers to U+224C in HTML (“backward congruent” in entity documentation).
