HTML - <var> Tag

The HTML <var> tag stands for variable element; this tag represents the name of variable in a mathematical expression or a programming context.

The content inside the <var> tag is typically in italic font in most browsers, but we can override or change the content of the <var> tag by using the CSS properties.

Syntax

Following is the syntax of <var> tag −

<var>.....</var>

Example

In the following example, we are creating an HTML document and using the <var> tag to create a distributive law, as follows − 

<!DOCTYPE html>
<html>
<head>
   <title>HTML var tag</title>
</head>
<body>
   <h2>Example of var tag</h2>
   <p>Equation for distributive law</p>
   <p>
      <var>a</var>( <var>b</var>+ <var>c</var>)= <var>ab</var>+ <var>ac</var>
   </p>
</body>
</html>

When we run the above code, it will generate an output consisting of the text displayed on the webpage.

Example

Considering the following example, we are creating an HTML document and using the <var> tag to display the mathematics formula.

<!DOCTYPE html>
<html>
<head>
   <title>HTML var tag</title>
   <style>
      var {
         font-weight: bold;
      }
   </style>
</head>
<body>
   <p>The volume of a box is <var>l</var> × <var>w</var> × <var>h</var>, where <var>l</var> represents the length, <var>w</var> the width and <var>h</var> the height of the box. </p>
</body>
</html>

On running the above code, the output window will pop up displaying the text on the webpage.

Example

Let's look at the following example, where we are going to use the <var> tag to display the mathematical equation.

<!DOCTYPE html>
<html>
<head>
   <title>HTML var tag</title>
   <style>
      var {
         font-weight: bold;
      }
   </style>
</head>
<body>
   <p>A simple equation: <var>x</var> = <var>y</var> + 2 </p>
</body>
</html>

When we run the above code, it will generate an output consisting of the text displayed on the webpage.

Following are some related tag of <var> tag, which can also be used for the same context −

  • <code> − to determine the computer programming
  • <kbd> − To determine the keyboard input.
  • <samp> − To determine the sample output.
