What You'll Learn

How to display Cross Below (Combining X Below, U+0353) in HTML and CSS. This is a combining character in the Combining Diacritical Marks block (U+0300–U+036F). It places an x-like mark below the preceding base letter—for example, a͓ renders when fonts support combining marks.

There is no named HTML entity for U+0353. Use ͓, ͓, or \353 in CSS content. Always place the combining mark after the base character in HTML. Pair with Cross Above (U+033D) when you need the mark above the letter instead of below.

Use Cases

Cross Below (͓) commonly appears in:

💬 Linguistics

IPA, phonetic notation, transliteration, and language documentation.

😀 Typography

Scholarly editions and custom glyphs using combining diacritics.

📚 Academic papers

Linguistics, philology, and ancient-script publications.

📄 Unicode docs

Font design, character references, and i18n tooling.

💻 Generated HTML

CMS or tools outputting specialized diacritical sequences.

😀 Symbol references

Unicode tables and combining-mark glossaries.

♿ Accessibility

Describe the diacritic in text; combining marks can be hard for screen readers alone.

💡 Best Practices

Do

  • Place U+0353 after the base character (e.g. a&#x0353;)
  • Use &#x0353; or &#851; for the combining mark
  • Choose fonts that support Combining Diacritical Marks
  • Use \353 only inside CSS content (with a base character when needed)
  • Keep hex or decimal style consistent across the document

Don’t

  • Put the combining mark before the base letter (order matters)
  • Confuse U+0353 with multiplication U+00D7 (×) or letter x
  • Assume a named entity exists—U+0353 has none
  • Put CSS escape \353 in HTML text nodes
  • Expect every font to render rare combining marks identically

Key Takeaways

1

No named entity—use numeric references

&#x0353; &#851;
2

For CSS stylesheets, use the escape in the content property
