How It Works
1. Hex:☽ inserts code point U+263D → ☽.
2. Decimal: same code point as 9789 → ☽. Same visual as hex.
3. CSS: use \263D in content (not an HTML entity). #point::after appends ☽.
4. Typed: paste ☽ in a UTF-8 document, or place it next to a phase label.
Pitfalls & Tips
Common mistakes when working with First quarter moon.
Name
No named entity
There is no HTML5 named entity for U+263D. Use ☽ or ☽. Do not invent &moon;.
☾
Not last quarter
U+263E (☾) is the last quarter moon — the opposite phase glyph.
Emoji
Not emoji moons
Emoji moon pictographs live in a different Unicode block and may render as colorful emoji. U+263D is a classic text symbol.
Font
Font coverage
Miscellaneous Symbols glyphs may be missing in some fonts. Prefer a font with symbol coverage, or use an image/SVG if the glyph must always render.
CSS vs HTML
Do not mix escapes
\263D belongs in CSS strings. ☽ / ☽ belong in HTML.

Add accessible text
Screen readers may not announce ☽ clearly. Prefer nearby prose (for example “First quarter moon”) when the symbol carries meaning.
Semicolon
End references
Always finish entities with ; — write ☽, not ☽.
