CSS, Javascript, and jQuery all borrow from the same method of selecting an element with a specified attribute.
In the example below, elements with the TITLE attribite will be styled.
$("[title]").addClass("btn btn-success btn-lg");
In this example below, only the button with a TYPE=BUTTON attribite will be styled.
$("[type=button]").addClass("btn btn-danger btn-lg");
