What Is the Seagull Below Entity?

Seagull Below is the Combining Diacritical Marks character at Unicode U+033C (COMBINING SEAGULL BELOW). It is a non-spacing mark — it attaches under the letter that comes before it (for example a̼ → a̼).

Remember
Example       a̼
Unicode       U+033C
Hex entity    ̼
Decimal       ̼
Named entity  (none)
CSS escape    \33C
Not the same  ḁ (ring below) · a̹ (right half ring below)

Always place the entity after a base character. Prefer ̼ when you want an explicit combining entity. For a simple ring under a letter, see Ring Below.

Three ways to put Seagull Below on a (no named entity).

html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Seagull Below (a̼)</title>
  <style>
    #point::after {
      content: "\33C";
    }
  </style>
</head>
<body>
  <p>Using Hex Code: a&#x033C;</p>
  <p>Using HTML Code: a&#828;</p>
  <p id="point">Using CSS Entity: a</p>
  <p><code>Sample: e&#x033C;</code></p>
</body>
</html>
Try It Yourself

How It Works

1. Hex: write a base letter, then &#x033C;. The mark combines under that letter → a̼.

2. Decimal: same code point as 828 → a&#828;. Same result as hex.

3. Named: HTML5 does not define a named entity for U+033C — use hex or decimal instead.

4. CSS: use \33C in content. Here #point ends with a, and ::after appends the combining mark so it sits under that letter.

Pitfalls & Tips

Common mistakes when working with Seagull Below.

Combining

Needs a base letter

Do not use &#x033C; alone. Write a&#x033C;, e&#x033C;, etc.

Order

Base first, mark second

Wrong: &#x033C;a. Right: a&#x033C;.

Named

No &…; name

Do not invent a name. Use &#x033C; or &#828;.

Fonts

Glyph coverage

Combining marks need good font support. Test stacking on your target devices — some fonts omit U+033C.

CSS vs HTML

Do not mix escapes

\33C belongs in CSS. &#x033C; / &#828; belong in HTML after a base letter.

Semicolon

End references

Always finish with ; — write &#x033C;, not &#x033C.

Browser Support

Seagull Below (U+033C) and its entity forms (&#x033C;, &#828;, CSS \\33C) are supported in all modern browsers when placed after a base letter. Glyph coverage depends on the font.

Key Takeaways

  • Unicode: this mark is U+033C (decimal 828) — combining, under the letter.
  • HTML: prefer a&#x033C; — or use a&#828;. No named entity.
  • CSS: use \33C in content after a base letter.
  • Watch out: never use the mark alone — always pair it with a base character.

One line: base + U+033C → a&#x033C; / a&#828; / CSS \33C (no named entity).
