What You'll Learn

How to display the Down Tack Below (̞) in HTML using hexadecimal, decimal, and CSS escape methods. This character is U+031E (COMBINING DOWN TACK BELOW) in the Combining Diacritical Marks block (U+0300–U+036F)—a combining mark placed below a base character, used in phonetic notation (e.g. IPA) and mathematical or logical diacritics.

Render it with ̞, ̞, or CSS escape \31E after a base letter (e.g. a̞). There is no named HTML entity. For the non-combining down tack use ⊤ (U+22A4).

🧠 How It Works

1

Hexadecimal Code

&#x31E; uses the Unicode hexadecimal value 31E to display the Down Tack Below. The x prefix indicates hexadecimal format.

HTML markup
2

Decimal HTML Code

&#798; uses the decimal Unicode value 798 to display the same character.

HTML markup
3

CSS Entity

\31E is used in CSS stylesheets, particularly in the content property of pseudo-elements like ::before and ::after.

Same visual result

All three methods produce: ̞. Unicode U+031E. No named HTML entity—use numeric codes in markup. Serve HTML as UTF-8.

Use Cases

The Down Tack Below (̞) is commonly used in:

🎤 Phonetics

IPA and phonetic transcription with marks below letters.

📝 Linguistics

Dialect notation and specialized orthographies.

∑ Math diacritics

Combining marks in mathematical or logical notation.

📖 Typography

Specialized fonts and publishing workflows.

💻 Web content

Language-learning sites and linguistic reference pages.

📜 Dictionaries

Pronunciation guides that use combining diacritics.

💡 Best Practices

Do

  • Use &#x31E; or &#798; consistently in markup
  • Place ̞ immediately after the base character it modifies
  • Add aria-label or explain combining marks for screen reader users
  • Use \31E in CSS ::after on the base letter span
  • Serve pages with UTF-8 (<meta charset="utf-8">)

Don’t

  • Expect a named entity—none exists for U+031E
  • Confuse ̞ (combining below) with ⊤ (down tack symbol, U+22A4)
  • Use ̞ without a preceding base character in normal text
  • Put CSS escape \31E in HTML text nodes without a base glyph
  • Assume all fonts render combining marks correctly on every base letter

Key Takeaways

1

Two HTML numeric references render ̞

&#x31E; &#798;
2

For CSS stylesheets, use the escape in the content property
