What You'll Learn

How to display Contains As Member Small (∍) in HTML and CSS. This character is U+220D (SMALL CONTAINS AS MEMBER) in the Mathematical Operators block (U+2200–U+22FF). It is the small variant of Contains As Member U+220B (∋) and denotes that a set contains an element (the reverse of “element of” ∈).

There is no named HTML entity for U+220D. Use ∍, ∍, or \220D in CSS content. Use math fonts for clear rendering. Do not confuse ∍ with the regular contains-as-member ∋ or element-of ∈.

Complete HTML Example

This example shows U+220D using hexadecimal and decimal character references, plus a CSS content escape. There is no named HTML entity:

html
<!DOCTYPE html>
<html>
<head>
 <style>
  #point:after{
   content: "\220D";
  }
 </style>
</head>
<body>
<p>Contains As Member Small using Hexa Decimal: &#x220D;</p>
<p>Contains As Member Small using HTML Code: &#8717;</p>
<p id="point">Contains As Member Small using CSS Entity: </p>
</body>
</html>

vs element-of ∍ (contains)   ∈ (element of)
Monospace refs &#x220D; &#8717; \220D

🧠 How It Works

1

Hexadecimal Code

&#x220D; references code point U+220D using hex digits 220D.

HTML markup
2

Decimal HTML Code

&#8717; is the decimal equivalent (8717) for the same character.

HTML markup
3

CSS Entity

\220D is the CSS escape for U+220D, used in the content property of ::before or ::after.

CSS stylesheet
=

Same visual result

All three methods produce the small contains-as-member glyph: . Unicode U+220D is the small variant of U+220B (∋). No named HTML entity exists.

Use Cases

Contains As Member Small (∍) commonly appears in:

📊 Set theory

Compact “contains as member” notation where a smaller glyph fits inline.

📚 Math education

Discrete mathematics courses, textbooks, and online references.

🔢 Logic & CS

Formal logic, computer science docs, and set-operation explanations.

📄 Academic papers

Typography that prefers the small variant for consistency or space.

💻 Generated HTML

Tools outputting math symbols without MathML.

🔤 Symbol references

Unicode tables and Mathematical Operators glossaries.

♿ Accessibility

Explain meaning in surrounding text; do not rely on the glyph alone for screen readers.

💡 Best Practices

Do

  • Use &#x220D; when you need the small contains-as-member glyph
  • Use math fonts (Cambria Math, STIX Two Math) for clear operators
  • Pick ∍ or ∋ consistently for typography in one document
  • Use \220D only inside CSS content
  • Consider MathML for full equations; entities work for inline symbols

Don’t

  • Confuse U+220D (∍) with U+220B (∋) or U+2208 (∈)
  • Use ∍ for logical “and” or generic containment in prose
  • Assume every font distinguishes small and regular variants clearly
  • Put CSS escape \220D in HTML text nodes
  • Expect a named entity—U+220D has none

Key Takeaways

1

No named entity—use numeric references

&#x220D; &#8717;
2

For CSS stylesheets, use the escape in the content property

\220D

❓ Frequently Asked Questions

Use &#x220D; (hex), &#8717; (decimal), or \220D in CSS content. There is no named HTML entity for U+220D.
U+220D (SMALL CONTAINS AS MEMBER). Mathematical Operators (U+2200–U+22FF). Hex 220D, decimal 8717.
When you need the small variant ∍ in set theory, compact inline formulas, or documentation that prefers the smaller glyph over the regular contains-as-member ∋.
U+220B (∋) is CONTAINS AS MEMBER; U+220D (∍) is the small variant with the same meaning but a smaller glyph, often used in tight inline notation.
HTML5 named entities do not cover most specialized math operators. Use numeric codes. Element-of uses &isin; for U+2208, but U+220D has no named equivalent.
