The <var> HTML element represents the name of a variable in a mathematical expression or a programming context. It's typically presented using an italicized version of the current typeface, although that behavior is browser-dependent.

This element only includes the global attributes.

Other elements that are used in contexts in which <var> is commonly used include:

• <code>: The HTML Code element
• <kbd>: The HTML Keyboard input element
• <samp>: The HTML Sample Output element

If you encounter code that is mistakenly using <var> for style purposes rather than semantic purposes, you should either use a <span> with appropriate CSS or, an appropriate semantic element among the following:

• <em>
• <i>
• <q>

Most browsers apply font-style to "italic" when rendering <var>. This can be overridden in CSS, like this:

var {
  font-style: normal;
}

Here's a simple example, using <var> to denote variable names in a mathematical equation.

<p>A simple equation: <var>x</var> = <var>y</var> + 2</p>

Using CSS, you can override the default style for the <var> element. In this example, variable names are rendered using bold Courier if it's available, otherwise it falls back to the default monospace font.

CSS

var {
  font:
    bold 15px "Courier",
    "Courier New",
    monospace;
}

HTML

<p>
  The variables <var>minSpeed</var> and <var>maxSpeed</var> control the minimum
  and maximum speed of the apparatus in revolutions per minute (RPM).
</p>

This HTML uses <var> to enclose the names of two variables.
