Normal subgroup of (⊳) is the Mathematical Operators character at Unicode U+22B3 (CONTAINS AS NORMAL SUBGROUP). In group theory, G ⊳ H means G contains H as a normal subgroup — the reverse of H ⊲ G. HTML5 provides ⊳ and ⊳.
Remember
Character ⊳
Unicode U+22B3
Named entity ⊳ (also ⊳)
Hex entity ⊳
Decimal ⊳
CSS escape \22B3
All of these produce the same glyph: ⊳. Prefer ⊳ for readable HTML; paste ⊳ in UTF-8 when convenient.

How It Works
1. Named:⊳ (or ⊳) is the clearest HTML form for U+22B3.
2. Hex:U+22B3 → ⊳ in HTML. Reliable numeric form.
3. Decimal: same code point as 8883 → ⊳. Same glyph.
4. Direct: paste ⊳ in a UTF-8 file with <meta charset="UTF-8">.
5. CSS: use \22B3 in content (not an HTML entity). #point::after appends that ⊳ after the paragraph text.
Pitfalls & Tips
Common mistakes when working with this algebra entity.
Direction
⊳ vs ⊲
G ⊳ H means G contains H as normal. The reverse symbol is ⊲ (U+22B2).
Not superset
Not ⊃
Superset ⊃ is set inclusion. This symbol is a group-theory relation — different meaning.
Aliases
⊳ = ⊳
Both named forms map to U+22B3. Pick one and stay consistent.
CSS vs HTML
Do not mix escapes
\22B3 belongs in CSS. ⊳ / ⊳ / ⊳ belong in HTML.
Semicolon
End references
Always finish with ; — write ⊳, not &vrtri.
UTF-8
Declare charset
If you paste ⊳ directly, serve the page as UTF-8 with <meta charset="UTF-8">.
Compatibility
Browser Support
Normal subgroup of (U+22B3) and its entity forms (⊳, ⊳, ⊳, CSS \\22B3) are supported in all mainstream browsers. Glyph availability depends on the font.
✓ Universal support
Normal Subgroup 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 \\22B3 only inside CSS content.

Key Takeaways
Unicode: contains as normal subgroup is U+22B3 (decimal 8883), Mathematical Operators.
HTML: prefer ⊳ (alias ⊳), or ⊳ / ⊳.
Use ⊳ or ⊳ (named), ⊳ (hex), ⊳ (decimal), type ⊳ in UTF-8, or the CSS escape \22B3 in content. All render ⊳.
U+22B3 (CONTAINS AS NORMAL SUBGROUP). Hex 22B3, decimal 8883. It belongs to Mathematical Operators and is the reverse of U+22B2 (⊲).
Yes. HTML5 defines ⊳ and ⊳ (aliases for the same character). You can also use ⊳ or ⊳.
Use it in abstract algebra for the “contains as normal subgroup” relation (G ⊳ H). Prefer ⊳ for readable source. For ordinary English, write the relation in words.
HTML entities (⊳, ⊳, or ⊳) go in markup. The CSS escape \22B3 is used in stylesheets (usually in the content property of ::before/::after). Both render ⊳.
U+22B2 (⊲) is the reverse relation (is a normal subgroup of). Superset ⊃ (U+2283, ⊃) is set inclusion, not the normal-subgroup relation. Do not substitute one for another.

Did you know?
Normal subgroup of (⊳) is Unicode U+22B3 (decimal 8883) — CONTAINS AS NORMAL SUBGROUP in Mathematical Operators. HTML5 provides ⊳ (also ⊳). In group theory, G ⊳ H means G contains H as a normal subgroup (same relation as H ⊲ G).
