 In this tutorial we will present the key features of RenoirSt with a large set of examples.
 This tutorial assumes some knowledge of CSS and Pharo Smalltalk. For a little introduction about CSS you can read the *Seaside's book CSS chapter>http://book.seaside.st/book/fundamentals/css*.

-Beautiful! you have now an inspector on your first (empty and useless) style sheet. Let's do now something more useful. Real stylesheets are composed of rules (or rule-sets), where each one has a selector and a declaration group. The selector determines if the rule applies to some element in the DOM, and the declaration group specifies the style to apply.

 So far our focus was on the style part of the rule. Let's focus now on the available selectors. Remember that a CSS selector represents a structure used to match elements in the document tree.

 You should not hardcode the classes and ids, they should be obtained from the same object that holds them for the HTML generation. You probably have some code setting the class(es) and/or id(s) to a particular HTML element.

 The pseudo-class concept is introduced to allow selection based on information that lies outside of the document tree or that cannot be expressed using the simpler selectors. Most pseudo-classes are supported just by sending one of the following messages link, visited, active, hover, focus, target, enabled, disabled or checked.

 The :nth-child(an\+b) pseudo-class notation represents an element that has an\+b\-1 siblings before it in the document tree, for any positive integer or zero value of n, and has a parent element. For values of a and b greater than zero, this effectively divides the element's children into groups of a elements (the last group taking the remainder), and selecting the bth element of each group. The a and b values must be integers (positive, negative, or zero). The index of the first child of an element is 1.

 Pseudo-elements create abstractions about the document tree beyond those specified by the document language. For instance, document languages do not offer mechanisms to access the first letter or first line of an element's content.
