HTML Entity for Double Grave Accent (̏)
What You'll Learn
How to encode U+030F (combining double grave accent) in HTML and CSS. This mark combines with the preceding character—for example ȍ renders as ȍ (short falling tone in Serbo-Croatian and Slovene) and is used in the IPA for extra-low tone.
It is defined in the Combining Diacritical Marks block (U+0300–U+036F). There is no named HTML entity for U+030F; use ̏, ̏, or \030F in CSS strings. Do not confuse with double acute (U+030B, Hungarian ő/ű) or single combining grave (U+0300).

This example attaches U+030F after base letters using hex, decimal, and a CSS content string (ȍ, ȁ):
<!DOCTYPE html>
<html>
<head>
<style>
#point:after{
content: "o\030F";
}
</style>
</head>
<body>
<p>Double grave (decimal on a): ȁ</p>
<p id="point">Double grave (CSS entity): </p>
</body>
</html>🌐 Browser Support
Numeric references for U+030F are supported in all modern browsers. Stacking quality depends on font support for combining marks:

🧠 How It Works
Hexadecimal Code
̏ references Unicode 030F in hex. Write it immediately after the base letter (for example ȍ).
Decimal HTML Code
̏ is decimal 783, equivalent to U+030F.
CSS Entity (Escape)
\030F inside a CSS string (for example content: "o\030F") emits the same combining sequence in generated content.
Same visual result
With base o or a, all methods yield ȍ or ȁ. Place U+030F immediately after the base letter. No named entity for U+030F.
Use Cases
The combining double grave accent (U+030F) is commonly used in:
Short falling tone in phonetic or orthographic discussion (e.g. ȍ, ȁ).
International Phonetic Alphabet notation for extra-low tone on vowels.
Academic papers, dictionaries, and language-learning sites with tone diacritics.
When precomposed Cyrillic with double grave is unavailable, U+030F follows the base letter.
HTML entity lists and Unicode tables for combining marks.
Ensure fonts cover U+0300–U+036F so base + U+030F stacks correctly for all users.
💡 Best Practices
Do
- Keep base letter and U+030F adjacent in the DOM (base first)
- Use UTF-8 and pick NFC or NFD consistently for your product
- For some Latin letters, check for precomposed forms (e.g. U+020D) before using U+030F
- Test fonts and line-breaking so the accent does not separate from its letter
- Use
\030Fonly inside CSS strings, not as raw HTML text
Don’t
- Place U+030F before the base letter (wrong order for Unicode)
- Confuse double grave (U+030F) with double acute (U+030B) or single grave (U+0300)
- Rely on CSS
contentfor entire paragraphs of accented prose - Mix NFC and NFD arbitrarily in the same database column without a plan
- Assume every decorative webfont positions combining marks perfectly

❓ Frequently Asked Questions
̏ (hex) or ̏ (decimal) after the base letter, e.g. ȍ for ȍ. In CSS, content: "o\030F" is a common pattern. There is no standard named entity for U+030F.U+030F (hex 030F, decimal 783). It combines with the preceding character and lives in the Combining Diacritical Marks block.\030F belongs in stylesheet strings. Same code point, different layer.o + U+030F = ȍ). In HTML, place the entity right after the base with no space: ȍ or ȍ.Explore More HTML Entities!
