This script checks if the first of the results (the set of elements matching the selector of the
script) has the class 'green'. If so, it colors the text of all the elements in the results green.
if (results.hasClass('green')) {
results.css('color', 'green');
}
height()
Gets or sets the outer height, including padding and borders, of the first element in the results
(see "results" on page902), i.e. the set of HTML elements that match the selector of the script or
of another query in the template (see "query()" on page863).

The returned value is the height in pixels, without measurement unit (e.g. 400).

include margins, call height(value, true).
