What Is Small Contains Overbar?

Small contains overbar (⋾) is the Unicode character at U+22FE in Mathematical Operators. Official name: SMALL CONTAINS WITH OVERBAR. It is a set-theory style relation used in mathematical notation.

Remember
Character     ⋾
Unicode       U+22FE
Named entity  ⋾
Hex entity    ⋾
Decimal       ⋾
CSS escape    \22FE
Not the same  ⋽ · ∍ · ⋼

Prefer ⋾ in HTML markup. You can also type ⋾ in UTF-8, or use numeric forms when needed. Use a math-capable font for the clearest glyph.

<!DOCTYPE html>
<html lang="en">

  <meta charset="UTF-8">

  <p>Using HTML Code: &#8958;</p>

Try It Yourself

How It Works

1. Named: &notnivb; is the HTML5 name for U+22FE → ⋾. Best default in markup.

2. Hex: U+22FE → &#x22FE; in HTML. Same glyph as the named form.

3. Decimal: same code point as 8958 → &#8958;. Same result as hex and named.

4. CSS: use \22FE in content (not an HTML entity). #point::after appends that ⋾ after the paragraph text.

5. Typed / math: paste ⋾ in UTF-8, or write A &notnivb; B for a simple relation example.

Pitfalls & Tips

Common mistakes when working with &notnivb;.

vs ⋽

Not contains overbar

U+22FD (⋽) is contains with overbar. U+22FE is the small form — different characters.

vs ∍

Not small contains member

∍ (U+220D) is small contains as member. Do not swap it with &notnivb;.

Name

Remember &notnivb;

The named entity is &notnivb; — not &nivb; or &notni;.

CSS vs HTML

Do not mix escapes

\22FE belongs in CSS strings. &notnivb; / &#x22FE; / &#8958; belong in HTML.

Semicolon

End named entities

Always finish with ; — write &notnivb;, not &notnivb.

Fonts

Use a math font

Some UI fonts omit U+22FE. Prefer Cambria Math, STIX, or similar for readable operators.

Browser Support

Small contains overbar (U+22FE) and its entity forms (&notnivb;, &#x22FE;, &#8958;, CSS \\22FE) are supported in all mainstream browsers. Visible glyphs depend on Mathematical Operators font coverage.

✓ Universal support

Small Contains Overbar (&#x22FE;)

Encode with named, hex, decimal, CSS escape, or type the character — same code point everywhere encoding is supported.

Bottom line: Prefer &notnivb; in HTML. Use &#x22FE; / &#8958; when numeric form is required, and \\22FE only inside CSS content.

Key Takeaways

  • Unicode: small contains overbar is U+22FE (decimal 8958) — glyph ⋾.
  • HTML: prefer &notnivb; — also &#x22FE; / &#8958; / type ⋾.
  • CSS: use \22FE inside content for generated text.
  • Meaning: ⋾ is the small overbar form — not ⋽, not ∍, not ⋼.

One line: U+22FE → &notnivb; / &#x22FE; / &#8958; / CSS \22FE.

Frequently Asked Questions

Use &notnivb; (named), &#x22FE; (hex), &#8958; (decimal), type ⋾ directly in UTF-8, or the CSS escape \22FE in content. Prefer &notnivb; in normal HTML.
U+22FE (SMALL CONTAINS WITH OVERBAR). Hex 22FE, decimal 8958. It belongs to the Mathematical Operators block (U+2200–U+22FF).
Yes. Use &notnivb;. Numeric forms &#8958; and &#x22FE; also work.
No. ⋾ is U+22FE (&notnivb;). Related but different: U+22FD (contains with overbar), U+220D (small contains as member), and U+22FC (small contains with vertical bar).
Use it in set theory and math documentation when you need the small contains-with-overbar operator. Prefer a math-capable font for clear glyphs.
HTML entities (&notnivb;, &#8958;, or &#x22FE;) go in markup. The CSS escape \22FE goes in stylesheet strings (usually content on ::before/::after).

Did you know?

Small contains overbar is Unicode U+22FE (decimal 8958) — glyph ⋾ in Mathematical Operators. HTML5 names it &notnivb;. Official name: SMALL CONTAINS WITH OVERBAR. Do not confuse with contains overbar U+22FD (⋽) or small contains member U+220D (∍).
