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), we created a selector that has an exact match. To remind you, this was the selector we've built:

button[class='pure-button pure-button-primary-progressive'][type='submit']

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


Note how exact value of pure-button pure-button-primary-progressive was shortened to the loosely matching value pure-button.
