Digit seven (7) is the Basic Latin character at Unicode U+0037. You can type 7 directly in HTML, or write it with a numeric character reference when you need an explicit entity form.
Remember
Character 7
Unicode U+0037
Hex entity 7
Decimal 7
CSS escape \0037
Named entity (none)
All of these produce the same glyph: 7. Prefer typing 7 in normal page text; use entities for CSS content, generated markup, or when encoding must be explicit.

How It Works
1. Hex:U+0037 → 7 in HTML. The browser turns it into 7.
2. Decimal: same code point as 55 → 7. Same result as hex.
3. CSS: use \0037 in content (not an HTML entity). #point::after appends that 7 after the paragraph text.
4. Typed 7: best for normal text. All four lines show the same digit.
Pitfalls & Tips
Common mistakes when working with digit seven entities.
Named?
No &seven;
HTML5 does not define a named entity for ASCII digits. Use numeric forms.
CSS vs HTML
Do not mix escapes
\0037 belongs in CSS. 7 / 7 belong in HTML.
Lookalikes
Related forms differ
Circled or dingbat sevens (such as ➆) are different Unicode characters — not the same as U+0037.
Default
Type 7 when you can
Entities are for encoding needs — not required for ordinary body text.
Semicolon
End references
Always finish with ; — write 7, not 7.
CSS escape
Pad short hex
In CSS content, prefer \0037 (six hex digits) so the escape does not swallow the next character.

Use entities when generating content in CSS, when you want explicit encoding, or when outputting into contexts where escaping is required. For normal body text, typing 7 directly is usually best.
HTML entities (7 or 7) go in markup. The CSS escape \0037 is used in stylesheets (usually in the content property of ::before/::after). Both render 7.
