Description: Selects elements that have the specified attribute with a value containing the a given substring.
This is the most generous of the jQuery attribute selectors that match against a value. It will select an element if the selector's string appears anywhere within the element's attribute value. Compare this selector with the Attribute Contains Word selector (e.g. [attr~=word]), which is more appropriate in many cases.
