<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Reverse Double Prime (‶) in HTML</title>
  <style>
    #point::after {
      content: "\2036";
    }
  </style>
</head>
<body>
  <p>Reverse Double Prime using Hex Code: &#x2036;</p>
  <p>Reverse Double Prime using HTML Code: &#8246;</p>
  <p id="point">Reverse Double Prime using CSS Entity: </p>
  <p>Typed directly: ‶</p>
  <p>Compare: reverse ‶ vs double &Prime;</p>
</body>
</html>
Try It Yourself

How It Works

1. Hex: U+2036 → &#x2036; in HTML. The browser turns it into ‶.

2. Decimal: same code point as 8246 → &#8246;. Same result as hex.

3. CSS: use \2036 in content (not an HTML entity). #point::after appends that ‶ after the paragraph text.

4. Typed / compare: paste ‶ in UTF-8, and use &Prime; when you need the standard (non-reversed) double prime.

Pitfalls & Tips

Common mistakes when working with Reverse Double Prime.

Named?

No named entity

HTML5 does not define &rdprime; or similar for U+2036. Use &#x2036; or &#8246;.

″

Not the same as &Prime;

&Prime; is double prime (″, U+2033). Reverse double prime is a different code point (U+2036).

‵

Single vs double reverse

&bprime; is reversed single prime (‵). Do not use it when you need the double form ‶.

""

Not two quotation marks

Typing "" or &quot;&quot; is not a reverse double prime. Use the real U+2036 character.

CSS vs HTML

Do not mix escapes

\2036 belongs in CSS strings. &#x2036; / &#8246; belong in HTML.

Semicolon

End numeric references

Always finish with ; — write &#8246;, not &#8246.

One line: U+2036 → &#x2036; / &#8246; / CSS \2036.
