HTML Entity for Element Of Underbar (⋸)
What You'll Learn
How to display the Element Of Underbar (⋸) in HTML using hexadecimal, decimal, and CSS escape methods. This character is U+22F8 (ELEMENT OF WITH UNDERBAR) in the Mathematical Operators block (U+2200–U+22FF)—a specialized variant related to standard set membership (∈, U+2208).
Render it with ⋸, ⋸, or CSS escape \22F8. There is no named HTML entity for this symbol. For the common element-of operator use ∈ (∈). Compare ⋵ (element of with dot above, U+22F5, ⋵) for another related variant.

🧠 How It Works
Hexadecimal Code
⋸ uses the Unicode hexadecimal value 22F8 to display the Element Of Underbar. The x prefix indicates hexadecimal format.
Decimal HTML Code
⋸ uses the decimal Unicode value 8952 to display the same character.
CSS Entity
\22F8 is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.
Same visual result
All three methods produce: ⋸. Unicode U+22F8 in the Mathematical Operators block (U+2200–U+22FF). No named HTML entity—use numeric codes in markup. Serve HTML as UTF-8.
Use Cases
The Element Of Underbar (⋸) is commonly used in:
Formal expressions and set-theory notation requiring this variant.
Advanced set theory, discrete math, and logic course materials.
Specialized membership or relation notation in proofs.
Type-theoretic and mathematical notation in technical writing.
Papers and preprints with correct operator variants in HTML.
Math wikis, Unicode references, and notation glossaries.
💡 Best Practices
Do
- Use
⋸or⋸consistently in markup - Use math-friendly fonts (Cambria Math, Latin Modern Math) for clear rendering
- Add
aria-label(e.g. “element of with underbar”) when meaning matters - Use
∈(∈) for standard set membership when that is sufficient - Serve pages with UTF-8 (
<meta charset="utf-8">)
Don’t
- Expect a named entity—none exists for U+22F8
- Substitute ⋸ for ∈ unless your notation specifically requires it
- Put CSS escape
\22F8in HTML text nodes - Assume plain sans-serif fonts always render math variants clearly
- Skip MathML for complex multi-line formulas
