Is there a named HTML entity for the digit zero?

No. ASCII digits like 0 do not have named HTML entities in HTML5, so you should use numeric references like 0 or 0 when you need an entity form.

When should I use the digit zero HTML entity?

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 0 directly is usually best.

What’s the difference between HTML code and CSS entity for 0?

HTML entities (0 or 0) go in markup. The CSS escape \0030 is used in stylesheets (usually in the content property of ::before/::after). Both render 0.

💡 Best Practices

Do

Type 0 directly in normal body content
Use entities when you need explicit encoding (CSS content, generated output, or special contexts)
Use monospace or tabular figures for aligned numeric UI
Include context so users don’t confuse 0 with O

Don’t

Assume there is a named entity for 0 (there isn’t)
Mix CSS escapes into HTML markup (use them in stylesheets only)
Overuse entities where a direct character is clearer
Use ambiguous fonts in UI where 0 and O look identical

Key Takeaways

Digit zero is Unicode U+0030

U+0030 0 0

For CSS stylesheets, use the escape in the content property

\0030

There is no named HTML entity for 0

Prefer typing 0 directly unless you need an entity form

❓ Frequently Asked Questions

How do I display the digit zero (0) in HTML using entities?

Use 0 (hex), 0 (decimal), or \0030 in CSS content. In most cases you can also type 0 directly.

What is the Unicode value for the digit zero?

U+0030 (hex 0030, decimal 48) in the Basic Latin (ASCII) block.

Is there a named HTML entity for 0?

No. HTML doesn’t define a named entity for ASCII digits like 0, so use numeric references when needed.

When should I use an entity for 0 instead of typing it?

Use entities in CSS generated content, when constructing HTML strings safely, or when you want explicit encoding. For regular text, typing 0 is simplest.

How do I avoid confusing 0 with the letter O?

Use fonts designed for UI or code (often with a slashed or dotted zero), and add context labels like “Count: 0”.
