What You'll Learn

How to display the Element Of With Long Horizontal Stroke (⋲) in HTML using hexadecimal, decimal, named entity, and CSS escape methods. This character is U+22F2 (ELEMENT OF WITH LONG HORIZONTAL STROKE) in the Mathematical Operators block (U+2200–U+22FF)—a variant of set membership related to standard element-of (∈, U+2208).

Render it with ⋲, ⋲, the named entity ⋲, or CSS escape \22F2. For standard membership use ∈ (∈). Compare ⋵ (dot above, U+22F5, ⋵) or ⋶ (overbar, U+22F6, ⋶).

Use Cases

The Element Of With Long Horizontal Stroke (⋲) commonly appears in:

📐 Set theory

Specialized membership or relation notation in proofs and expressions.

🎓 Education

Math textbooks, discrete math, and formal logic course materials.

📝 Logic

Formal logic, proof writing, and logical expression documentation.

💻 CS docs

Type systems, formal semantics, and set-theoretic technical writing.

📰 Research

Online math and CS publications with correct operator variants.

🌐 Math tools

Solvers, calculators, and formal logic UIs that output HTML.

💡 Best Practices

Do

  • Use &disin; for readable set-theory markup
  • Pick one style (hex / decimal / named) per project
  • Use math-friendly fonts (Cambria Math, Latin Modern Math)
  • Add aria-label (e.g. “element of with long horizontal stroke”) when meaning matters
  • Use &isin; (∈) when standard membership is sufficient

Don’t

  • Substitute ⋲ for ∈ unless your notation specifically requires it
  • Use CSS escape \22F2 inside HTML text nodes
  • Mix entity styles randomly in one file
  • Assume plain sans-serif fonts always render math variants clearly
  • Skip MathML for complex multi-line formulas

Key Takeaways

1

Three HTML references plus CSS all render ⋲

&#x22F2; &#8946; &disin;
2

For CSS stylesheets, use the escape in the content property
