How It Works
1. Named:⊪ is the preferred HTML5 name for U+22AA → ⊪ (capital V).
2. Hex:⊪ inserts the same code point. Same visual as named.
3. Decimal: same code point as 8874 → ⊪.
4. CSS: use \22AA in content (not an HTML entity). #point::after appends ⊪.
5. Typed: paste ⊪ in a UTF-8 document, or write Γ ⊪ φ for logic notation.
Pitfalls & Tips
Common mistakes when working with Triple Vertical Bar Right Turnstile.
Named
Prefer ⊪
⊪ is case-sensitive. Capital V then vdash — not &vvdash;, ⊩, ⊨, or ⊫.
Look-alikes
⊪ ≠ ⊨ ≠ ⊩ ≠ |||
U+22AA is one character. Do not fake it with three pipes. True is ⊨; double bar is ⊩.
A11y
Add context
A lone ⊪ may be unclear. Pair it with wording such as “triple vertical bar turnstile” or an accessible name for screen readers.
Fonts
Glyph coverage
Mathematical Operators coverage varies. Test logic pages on mobile and provide a MathML or image fallback if ⊪ is missing.
CSS vs HTML
Do not mix escapes
\22AA belongs in CSS. ⊪ / ⊪ / ⊪ belong in HTML.
Semicolon
End references
Always finish with ; — write ⊪, not &Vvdash.
Compatibility
Browser Support
Triple Vertical Bar Right Turnstile (U+22AA) and its entity forms (⊪, ⊪, ⊪, CSS \\22AA) are supported in all modern browsers. Glyph coverage depends on the font.

Key Takeaways
Unicode: this symbol is U+22AA (decimal 8874) — triple vertical bar right turnstile.
HTML: prefer ⊪ — or use ⊪ / ⊪.
CSS: use \22AA inside content for generated logic markers.
Watch out: not the same as ⊨, ⊩, or three pipes.
Use ⊪ (named), ⊪ (hex), ⊪ (decimal), or the CSS escape \22AA in the content property. All render ⊪. Prefer ⊪ for readable markup.
U+22AA (TRIPLE VERTICAL BAR RIGHT TURNSTILE). Hex 22AA, decimal 8874, named entity ⊪. It belongs to Mathematical Operators (U+2200–U+22FF).
Yes. HTML5 defines ⊪ for U+22AA. It is case-sensitive — write ⊪ (capital V), not &vvdash; or &VVDASH;.
U+22AA is TRIPLE VERTICAL BAR RIGHT TURNSTILE (⊪). U+22A8 is TRUE (⊨). U+22A9 is DOUBLE VERTICAL BAR RIGHT TURNSTILE (⊩). Same family, different bar counts — and different named-entity casing.
Use it for formal logic and mathematical notation that specifically needs the triple vertical bar right turnstile. Prefer ⊪ instead of three ASCII pipes (|||).
HTML entities (⊪, ⊪, or ⊪) go in markup. The CSS escape \22AA is used in stylesheets (usually in the content property of ::before/::after). Both render ⊪.
🤔
Did you know?
Triple Vertical Bar Right Turnstile is Unicode U+22AA (decimal 8874) — glyph ⊪ (TRIPLE VERTICAL BAR RIGHT TURNSTILE) in Mathematical Operators. HTML5 names it ⊪ (case-sensitive: capital V, then lowercase vdash). Prefer it for specialized logic notation. Do not confuse it with true (⊨, U+22A8) or double vertical bar right turnstile (⊩, U+22A9).
