HTML Entity for superset of (U+2283) tutorial illustration

Definition

What Is Superset Of?

Superset of (⊃) is the Unicode character at U+2283 in Mathematical Operators. Official name: SUPERSET OF. In set theory, A ⊃ B means every element of B is also in A. HTML5 provides the named entities ⊃ and &supset;.

Remember

Character     ⊃
Unicode       U+2283
Named entity  &sup;  (also &supset;)
Hex entity    &#x2283;
Decimal       &#8835;
CSS escape    \2283

All of these produce the same glyph: ⊃. Prefer ⊃ for readable HTML; paste ⊃ in UTF-8 when convenient.

Reference

Quick Reference

One table for every form you will actually use.

Form	Code	Where it goes
Named entity	`⊃`	HTML markup (preferred)
Named alias	`&supset;`	HTML markup (same glyph)
Hex entity	`⊃`	HTML markup
Decimal entity	`⊃`	HTML markup
Direct character	`⊃`	HTML text (UTF-8 default)
CSS escape	`\2283`	Stylesheet `content`

When to Use Which

Situation	Use
Superset of	`⊃` or `&supset;`
Subset of (reverse)	⊂ / `⊂`
Superset or equal to	⊇ / `&supe;`
Not a superset of	⊅ / `&nsup;`
UTF-8 math text	Type or paste `⊃`
Generated text via `::before` / `::after`	`content: "\2283"`

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Superset Of (⊃) in HTML</title>
  <style>
    #point::after {
      content: "\2283";
    }
  </style>
</head>
<body>
  <p>Using Named Entity: &sup;</p>
  <p>Using Hex Code: &#x2283;</p>
  <p>Using HTML Code: &#8835;</p>
  <p id="point">Using CSS Entity: </p>
  <p>Typed directly: ⊃</p>
  <p>Example: A &sup; B</p>
</body>
</html>

Try It Yourself

How It Works

1. Named: ⊃ (or &supset;) is the clearest HTML form for U+2283.

2. Hex: U+2283 → ⊃ in HTML. Same glyph as the named form.

3. Decimal: same code point as 8835 → ⊃. Same result as hex.

4. CSS: use \2283 in content (not an HTML entity). #point::after appends that ⊃ after the paragraph text.

5. Typed / example: paste ⊃ in UTF-8, or write A ⊃ B for a short set relation.

Pitfalls & Tips

Common mistakes when working with Superset Of.

⊂

Not subset of

⊂ is subset of (U+2282). Superset of is the reverse relation (U+2283).

⊇

Not superset or equal to

&supe; is U+2287. Prefer ⊃ when equality is not part of the relation.

Alias

`⊃` = `&supset;`

Both named forms map to U+2283. Pick one style and stay consistent.

Fonts

Math font coverage

Some UI fonts omit Mathematical Operators. Prefer a math-capable font for display.

CSS vs HTML

Do not mix escapes

\2283 belongs in CSS. ⊃ / ⊃ / ⊃ belong in HTML.

Semicolon

End entity references

Always finish with ; — write ⊃, not &sup.

Compatibility

Browser Support

Superset of (U+2283) and its entity forms (⊃, ⊃, ⊃, CSS \\2283) are supported in all mainstream browsers. Glyph availability depends on the font.

✓ Universal support

Superset Of (⊃)

Prefer ⊃, or encode with hex, decimal, or CSS escape — same glyph everywhere.

U+2283 / entities Full support

Bottom line: Prefer ⊃ (or &supset;) in HTML. Use ⊃ / ⊃ when a numeric form is required, and \\2283 only inside CSS content.

Remember

Key Takeaways

Unicode: this mark is U+2283 (decimal 8835) — glyph ⊃.
HTML: prefer ⊃ (alias &supset;), or ⊃ / ⊃.
CSS: use \2283 inside content for generated text.
Meaning: A ⊃ B means every element of B is in A — not ⊂, not ⊇.

One line: U+2283 → ⊃ / ⊃ / ⊃ / CSS \2283.

Frequently Asked Questions

How do I display ⊃ in HTML?

Use ⊃ or &supset; (named), ⊃ (hex), ⊃ (decimal), type ⊃ directly in UTF-8, or the CSS escape \2283 in content.

What is the Unicode value for this mark?

U+2283 (SUPERSET OF). Hex 2283, decimal 8835. It belongs to Mathematical Operators (U+2200–U+22FF).

Is there a named HTML entity for U+2283?

Yes. HTML5 defines ⊃ and the alias &supset; for this character. They are equivalent to ⊃ and ⊃.

When should I use U+2283?

Use it in set theory when A is a (proper or general) superset of B — every element of B is in A. Prefer &supe; for superset or equal to (U+2287) and &nsup; for not a superset of (U+2285).

What is the difference between HTML code and CSS entity for U+2283?

HTML entities (⊃, ⊃, or ⊃) go in markup. The CSS escape \2283 goes in stylesheet strings (usually content on ::before/::after).

Is ⊃ the same as ⊂ or ⊇?

No. ⊃ is superset of (U+2283). ⊂ is subset of (U+2282). ⊇ is superset or equal to (U+2287).

Did you know?

Superset of (⊃) is Unicode U+2283 (decimal 8835) — SUPERSET OF in Mathematical Operators. HTML5 provides ⊃ (also &supset;). In set theory, A ⊃ B means every element of B is also in A. Superset or equal is U+2287 (&supe;); the reverse is U+2282 (⊂).
