What Is the Left Right Double Arrow Vertical Stroke Entity?

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Left Right Double Arrow Vertical Stroke (⤄)</title>
  <style>
    #point::after {
      content: "\2904";
    }
  </style>
</head>
<body>
  <p>Using Hex Code: &#x2904;</p>
  <p>Using HTML Code: &#10500;</p>
  <p>Using Named Entity: &nvHarr;</p>
  <p id="point">Using CSS Entity: </p>
  <p><code>A &nvHarr; B</code></p>
</body>
</html>

Try It Yourself

How It Works

1. Hex: U+2904 → ⤄ in HTML. The browser turns it into ⤄.

2. Decimal: same code point as 10500 → ⤄. Same result as hex.

3. Named: &nvHarr; is the HTML5 name for this character. Capital H and A are required — spelling and case both matter.

4. CSS: use \2904 in content (not an HTML entity). #point::after appends that ⤄ after the paragraph text.

Pitfalls & Tips

Common mistakes when working with Left Right Double Arrow Vertical Stroke.

Look-alikes

⤄ ≠ ⇔ ≠ ⇎

&nvHarr; (vertical stroke), ⇔ (plain), and &nhArr; (diagonal stroke) are different characters.

Name

`&nvHarr;` ≠ `&nhArr;`

The v marks the vertical-stroke form. Case of H/A also matters.

Fonts

Glyph may be missing

Supplemental Arrows-B coverage varies. Test on your target devices or provide a fallback font.

CSS vs HTML

Do not mix escapes

\2904 belongs in CSS. &nvHarr; / ⤄ / ⤄ belong in HTML.

A11y

Add nearby words

Pair the glyph with equation text or use aria-label when it stands alone.

Semicolon

End references

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