🧠 How It Works
Hexadecimal Code
∊ references code point U+220A using hex digits 220A.
Decimal HTML Code
∊ is the decimal equivalent (8714) for the same character.
CSS Entity
\220A is the CSS escape for U+220A, used in the content property of pseudo-elements.
Same visual result
All three methods produce ∊. Unicode U+220A in Mathematical Operators. No named entity. Next: Small Element Of With Overbar.

Examples showing numeric references for U+220A.
Tools rendering math symbols without full MathML.
💡 Best Practices
Do
- Use
∊or∊in HTML markup - Use math fonts (Cambria Math, STIX Two Math) for clear operators
- Keep hex or decimal style consistent across a document
- Use CSS
content: "\220A"only in stylesheets - Distinguish ∊ from ∈ (element of) and ∍ (small contains)
Don’t
- Write U+0220A—the correct notation is U+220A
- Use CSS
\0220Awith a leading zero unless required—prefer\220A - Substitute
∈(U+2208) when ∊ is required - Expect a named HTML entity for U+220A
- Put CSS escape
\220Ain HTML text nodes
