<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Lowercase O Tilde (õ) in HTML</title>
  <style>
    #point::after {

Try It Yourself

How It Works

1. Named: &otilde; is the HTML5 name for U+00F5 → õ. Prefer this in markup.

2. Hex: &#xF5; inserts the same code point. Same visual as named.

3. Decimal: same code point as 245 → &#245;.

4. CSS: use \00F5 in content (not an HTML entity). #point::after appends õ.

5. Typed + sample: paste õ in UTF-8, or use &otilde; in Portuguese words like põe.

Pitfalls & Tips

Common mistakes when working with lowercase o with tilde.

Name

Prefer &otilde;

The named entity is clearer than inventing names — use &otilde; for U+00F5 in HTML.

Case

&otilde; ≠ &Otilde;

Named entities are case-sensitive. Lowercase is õ; uppercase is Õ.

ã

Not &atilde;

ã is a with tilde (common in Portuguese não). õ is o with tilde — different letter.

ȭ

Not tilde + macron

ȭ (U+022D) adds a macron on top of the tilde. See O Tilde Macron when that form is required.

CSS

Pad the CSS escape

Prefer \00F5 (four hex digits). A short \F5 can swallow the next hex digit if one follows immediately.

CSS vs HTML

Do not mix escapes

\00F5 belongs in CSS strings. &otilde; / &#xF5; / &#245; belong in HTML.

Semicolon

End references

Always finish entities with ; — write &otilde;, not &otilde.

Compatibility

Browser Support

Lowercase o with tilde (U+00F5) and its entity forms (&otilde;, &#xF5;, &#245;, CSS \\00F5) are supported in all mainstream browsers. Visible glyphs depend on Latin-1 / Western European font coverage.

Bottom line: Prefer &otilde; in HTML. Use &#xF5; / &#245; when numeric form is required, and \\00F5 only inside CSS content.

Remember

Key Takeaways

  • Unicode: lowercase o with tilde is U+00F5 (decimal 245) — glyph õ.
  • HTML: prefer &otilde; — also &#xF5; / &#245; / type õ.
  • CSS: use \00F5 inside content for generated text.
  • Watch out: &otilde; ≠ &Otilde; ≠ &atilde; ≠ ȭ.

One line: U+00F5 → &otilde; / &#xF5; / &#245; / CSS \00F5.
