Subset or equal to (⊆) is the Mathematical Operators character at Unicode U+2286 (SUBSET OF OR EQUAL TO). In set theory, A ⊆ B means A is a subset of B or the sets are equal. HTML5 provides the named entities ⊆ and ⊆.
Remember
Character ⊆
Unicode U+2286
Named entity ⊆ (also ⊆)
Hex entity ⊆
Decimal ⊆
CSS escape \2286
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+2286.
2. Hex:U+2286 → ⊆ in HTML. Reliable numeric form.
3. Decimal: same code point as 8838 → ⊆. Same glyph.
4. Direct: paste ⊆ in a UTF-8 file with <meta charset="UTF-8">.
5. CSS: use \2286 in content (not an HTML entity). #point::after appends that ⊆ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with Subset Or Equal To.
⊂
Not plain subset
⊂ (U+2282) is subset of without the equality bar. Use ⊆ when “or equal” is intended.
⊇
Not superset or equal
⊇ (U+2287) is the reverse relation. A ⊆ B is not the same as A ⊇ B.
Aliases
⊆ = ⊆
Both named forms map to U+2286. Pick one and stay consistent.
Named?
Named entities exist
Prefer ⊆ over numeric forms when readability matters — HTML5 defines both ⊆ and ⊆.
CSS vs HTML
Do not mix escapes
\2286 belongs in CSS. ⊆ / ⊆ / ⊆ belong in HTML.
Semicolon
End references
Always finish with ; — write ⊆, not &sube.
Compatibility
Browser Support
Subset or equal to (U+2286) and its entity forms (⊆, ⊆, ⊆, CSS \\2286) are supported in all mainstream browsers. Glyph availability depends on the font.
✓ Universal support
Subset Or Equal To (⊆)
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 \\2286 only inside CSS content.
Remember
Key Takeaways
Unicode: this mark is U+2286 (decimal 8838) — glyph ⊆.
HTML: prefer ⊆ (alias ⊆), or ⊆ / ⊆.
Use ⊆ (named), ⊆ (hex), ⊆ (decimal), type ⊆ directly in UTF-8, or the CSS escape \2286 in content. Alias: ⊆.
U+2286 (SUBSET OF OR EQUAL TO). Hex 2286, decimal 8838. 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 or A equals B (A ⊆ B). Prefer ⊂ for subset of without emphasizing equality (U+2282) and ⊇ for the reverse relation (U+2287).
HTML entities (⊆, ⊆, or ⊆) go in markup. The CSS escape \2286 goes in stylesheet strings (usually content on ::before/::after).
No. ⊆ is subset of or equal to (U+2286). ⊂ is subset of (U+2282). ⊇ is superset of or equal to (U+2287).
🤔
Did you know?
Subset or equal to (⊆) is Unicode U+2286 (decimal 8838) — SUBSET OF OR EQUAL TO in Mathematical Operators. HTML5 provides ⊆ (also ⊆). In set theory, A ⊆ B means A is a subset of B or the sets are equal. Plain subset is U+2282 (⊂); the reverse is U+2287 (⊇).
