# Exact or Loose Match

Instead of = to define the value of the attribute, you can use \*=. The sign = means exact match and \*= means loose match.

In the example of the Wikipedia's search button ([Basic Concepts of Selectors](/using-zerowork/using-selectors/how-to-build-custom-selectors/basic-concepts-of-selectors.md)), we created a selector that has an exact match. To remind you, this was the selector we've built:

<mark style="background-color:yellow;">button\[class='pure-button pure-button-primary-progressive']\[type='submit']</mark>

But if you use a loose match, the selector can look like this:

<mark style="background-color:yellow;">button\[class\*='pure-button']\[type='submit']</mark>

Note how exact value of *pure-button pure-button-primary-progressive* was shortened to the loosely matching value *pure-button*.&#x20;
