Var represents a variable or placeholder in mathematical or technical prose. It tells readers that a word stands for a value that might change.
What You Need to Know
It is not an HTML form control and does not create JavaScript variables. It labels meaning within the written explanation.
The goal is not to collect as many tags as possible. Pick the element that best describes what the content really is.
Example: See It in Action
Add this example to the appropriate part of a practice HTML page. Read each line before you open the page in your browser.
This is a short HTML fragment. To try it as a webpage, put it inside the body element of a complete HTML document.
<p>The area of a rectangle is <var>width</var> × <var>height</var>.</p>
<p>Here <var>width</var> means a changeable value.</p>
<p>Use this markup in explanations, not input forms.</p>Let’s Understand the Example
- Var identifies a variable, placeholder or mathematical symbol.
- A p groups a paragraph of related text. Start another paragraph for a new thought.
Look for the text “The area of a rectangle is” in the page. If the visible result surprises you, inspect the rendered elements to see what the browser actually built.
What Should You See?
The page should include “The area of a rectangle is”. If it looks different from what you expected, open developer tools and compare the source with the elements the browser created.
Try removing one piece of markup in a scratch copy, refresh the page, and compare the behavior. This is often the fastest way to understand what that piece contributes.
Try It Yourself
- Write a formula using two named quantities inside var.
- Save your changes, open or refresh the page, and compare the result with the original example.
- Tell a friend what your change did. If you are not sure, undo it, refresh the page, and compare.
Common Beginner Mistakes
- Expecting var in HTML to declare a working programming variable.
- Avoid picking tags just for their default bold, italic or spaced appearance. Use CSS for presentation.
