🅿️ HTML <var> Tag — Representing Variables in Text

The <var> tag in HTML is used to denote variables, or placeholders for values, in programming, mathematical expressions, or technical documentation. It indicates that the enclosed text is a variable name or symbol.

📌 What Is the <var> Tag?

  • Represents a variable or a placeholder in text.
  • An inline semantic element.
  • Helps clarify that the text is a variable, not regular content.
  • Typically rendered in an italic font by browsers by default.
  • Useful in technical writing, coding tutorials, and mathematical formulas.

✅ Basic Syntax

<p>The formula to calculate area is <var>A</var> = <var>l</var> × <var>w</var>, where <var>l</var> is length and <var>w</var> is width.</p>

🧪 Example: Using <var> in Code

<p>In JavaScript, you can declare a variable like this: <code>let <var>x</var> = 10;</code></p>

🎨 Styling <var>

By default, <var> is italicized, but you can customize it with CSS:

var {
  font-style: normal;
  color: blue;
  font-weight: bold;
}

⚠️ Best Practices

  • Use <var> only for variables or placeholders, not for emphasis or styling.
  • Combine <var> with <code> when showing variables in code snippets.
  • Avoid overusing <var> for non-technical content.
  • Ensure clarity by using <var> in appropriate contexts like documentation or math.

🏁 Summary

The <var> tag semantically marks variables or placeholders in HTML content. It improves the readability and meaning of technical and mathematical text by distinguishing variables visually and semantically.
