This script looks for an element with the ID box, appends a paragraph to it and colors all text
inside the box red.
query("#box").append("<p>Peter Parker</p>").css("color","red");

Note: the way the functions append() and css() are used in this script is called 'chaining'.
Chaining is optional; the same could be achieved by storing the result of the query in a
variable:
var box = query("#box");
box.append("<p>Peter Parker</p>");
box.css("color","red");
