Subset of (⊂) is the Mathematical Operators character at Unicode U+2282 (SUBSET OF). In set theory, A ⊂ B means every element of A is also in B. HTML5 provides the named entities ⊂ and ⊂.
Remember
Character ⊂
Unicode U+2282
Named entity ⊂ (also ⊂)
Hex entity ⊂
Decimal ⊂
CSS escape \2282
All of these produce the same glyph: ⊂. Prefer ⊂ for readable HTML; paste ⊂ in UTF-8 when convenient.
Using Named Entity: ⊂
Using Hex Code: ⊂
Using HTML Code: ⊂
Using Direct Character: ⊂
Using CSS Entity: ⊂
Example: A ⊂ B
How It Works
1. Named:⊂ (or ⊂) is the clearest HTML form for U+2282.
2. Hex:U+2282 → ⊂ in HTML. Reliable numeric form.
3. Decimal: same code point as 8834 → ⊂. Same glyph.
4. Direct: paste ⊂ in a UTF-8 file with <meta charset="UTF-8">.
5. CSS: use \2282 in content (not an HTML entity). #point::after appends that ⊂ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with Subset Of.
⊆
Not subset or equal
⊆ (U+2286) allows equality. ⊂ is the strict-looking subset relation without that bar.
⊃
Not superset
⊃ (U+2283) is the reverse relation. A ⊂ B is not the same as A ⊃ B.
Aliases
⊂ = ⊂
Both named forms map to U+2282. Pick one and stay consistent.
Negation
Not a subset
Use ⊄ (⊄, U+2284) when you need the negated relation.
CSS vs HTML
Do not mix escapes
\2282 belongs in CSS. ⊂ / ⊂ / ⊂ belong in HTML.
Semicolon
End references
Always finish with ; — write ⊂, not &sub.
Compatibility
Browser Support
Subset of (U+2282) and its entity forms (⊂, ⊂, ⊂, CSS \\2282) are supported in all mainstream browsers. Glyph availability depends on the font.
✓ Universal support
Subset Of (⊂)
Prefer ⊂, or encode with hex, decimal, or CSS escape — same glyph everywhere.

Bottom line: Prefer ⊂ (or ⊂) in HTML. Use ⊂ / ⊂ when a numeric form is required, and \\2282 only inside CSS content.
Remember
Key Takeaways
Unicode: this mark is U+2282 (decimal 8834) — glyph ⊂.
HTML: prefer ⊂ (alias ⊂), or ⊂ / ⊂.
Use ⊂ (named), ⊂ (hex), ⊂ (decimal), type ⊂ directly in UTF-8, or the CSS escape \2282 in content. Alias: ⊂.
U+2282 (SUBSET OF). Hex 2282, decimal 8834. It belongs to Mathematical Operators (U+2200–U+22FF).
Yes. HTML5 defines ⊂ and ⊂ for this character. Both are equivalent to ⊂ and ⊂.
Use it in set theory when A is a subset of B (A ⊂ B). Prefer ⊆ for subset or equal to (U+2286) and ⊃ for the reverse relation (U+2283).
HTML entities (⊂, ⊂, or ⊂) go in markup. The CSS escape \2282 goes in stylesheet strings (usually content on ::before/::after).
No. ⊂ is subset of (U+2282). ⊆ is subset of or equal to (U+2286). ⊃ is superset of (U+2283).
🤔
Did you know?
Subset of (⊂) is Unicode U+2282 (decimal 8834) — SUBSET OF in Mathematical Operators. HTML5 provides ⊂ (also ⊂). In set theory, A ⊂ B means every element of A is also in B. Subset or equal is U+2286 (⊆); the reverse is U+2283 (⊃).
