Definition

What Is the Right Tack Entity?

Right Tack (⊢) is the Mathematical Operators character at Unicode U+22A2 (RIGHT TACK). It is the turnstile used in logic and proof theory — often read as “proves” or entailment.

Remember

Character     ⊢
Unicode       U+22A2
Hex entity    &#x22A2;
Decimal       &#8866;
Named entity  &vdash;
CSS escape    \22A2
Not the same  &dashv; (⊣) · Right Tack Below (U+0319)

All of these produce the same glyph: ⊢. Prefer &vdash; when you want an explicit entity.

Reference

Quick Reference

One table for every form you will actually use.

Form	Code	Where it goes
Named entity	`&vdash;`	HTML markup (best entity default)
Hex entity	`⊢`	HTML markup
Decimal entity	`⊢`	HTML markup
CSS escape	`\22A2`	Stylesheet `content`
Direct character	`⊢`	UTF-8 HTML text

When to Use Which

Situation	Use
Readable HTML entity source	`&vdash;`
Need a numeric entity	`⊢` or `⊢`
Generated text via `::before` / `::after`	`content: "\22A2"`
Left tack (reverse turnstile)	Use &dashv; (U+22A3)
Combining diacritic below a letter	Use Right Tack Below (U+0319)

<!DOCTYPE html>

<head>
  <meta charset="UTF-8">
  <title>Right Tack (⊢)</title>
  <style>
    #point::after {
      content: "\22A2";
    }
  </style>
</head>
<body>
  <p>Using Hex Code: &#x22A2;</p>
  <p>Using HTML Code: &#8866;</p>
  <p>Using Named Entity: &vdash;</p>
  <p id="point">Using CSS Entity: </p>
  <p><code>A &vdash; B</code></p>
</body>
</html>

Try It Yourself

How It Works

1. Hex: U+22A2 → ⊢ in HTML. The browser turns it into ⊢.

2. Decimal: same code point as 8866 → ⊢. Same result as hex.

3. Named: &vdash; is the HTML5 name for this character.

4. CSS: use \22A2 in content (not an HTML entity). #point::after appends that ⊢ after the paragraph text.

Pitfalls & Tips

Common mistakes when working with Right Tack.

Look-alikes

⊢ ≠ ⊣

&vdash; faces right. &dashv; faces left. Pick the code point your notation needs.

Name

`&vdash;` ≠ `&dashv;`

The names are mirror images of each other — easy to swap by mistake.

Combining

Not a diacritic

U+22A2 is a spacing math operator. For a mark under a letter, use Right Tack Below (U+0319).

CSS vs HTML

Do not mix escapes

\22A2 belongs in CSS. &vdash; / ⊢ / ⊢ belong in HTML.

A11y

Add nearby words

Pair the glyph with label text (for example A &vdash; B) or use aria-label when it stands alone.

Semicolon

End references

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

Compatibility

Browser Support

Right Tack (U+22A2) and its entity forms (&vdash;, ⊢, ⊢, CSS \\22A2) are supported in all modern browsers. Glyph coverage depends on the font.

✓ Universal encoding

Right Tack (&vdash;)

Encode with named, hex, decimal, or CSS escape — or type ⊢ directly in UTF-8 HTML.

100% Browser coverage

Google Chrome Supported

Microsoft Edge Supported

U+22A2 / &vdash; Full support

Bottom line: Prefer &vdash; for readable HTML. Use \\22A2 only inside CSS content.

Remember

Key Takeaways

Unicode: this symbol is U+22A2 (decimal 8866).
HTML: prefer &vdash; — or use ⊢ / ⊢.
CSS: use \22A2 inside content for generated text.
Watch out: &vdash; ≠ &dashv;.

One line: U+22A2 → &vdash; / ⊢ / ⊢ / CSS \22A2.

Frequently Asked Questions

How do I display Right Tack (⊢) in HTML using entities?

Use &vdash; (named), ⊢ (hex), ⊢ (decimal), or the CSS escape \22A2 in the content property. You can also type ⊢ directly in UTF-8 HTML.

What is the Unicode value for Right Tack?

U+22A2 (RIGHT TACK). Hex 22A2, decimal 8866. It belongs to the Mathematical Operators block (U+2200–U+22FF).

Is there a named HTML entity for U+22A2?

Yes. &vdash; is the HTML5 named entity. You can also use ⊢ or ⊢.

When should I use this HTML entity?

Use it in logic, proof theory, and mathematical notation for a right tack (turnstile), often read as “proves” or entailment. Prefer &vdash; for readable HTML.

What is the difference between HTML code and CSS entity for U+22A2?

HTML entities (&vdash;, ⊢, or ⊢) go in markup. The CSS escape \22A2 is used in stylesheets (usually in the content property of ::before/::after). Both render ⊢.

How is &vdash; different from &dashv;?

&vdash; (U+22A2) is RIGHT TACK. &dashv; (U+22A3) is LEFT TACK — the mirrored form. They are not interchangeable.

Did you know?

Right Tack is Unicode U+22A2 (decimal 8866) — RIGHT TACK (the turnstile). HTML5 provides &vdash;. Prefer it for readable source. Do not confuse it with the left tack &dashv; (U+22A3) or the combining mark Right Tack Below (U+0319).
