Cascading Style Sheets (CSS) is a technology which allows personalized
presentation styles of document contents. It is based in textual source
code which has influence on the visual style and presentation of HTML and
XML documents. This includes ways of assigning layout and style properties,
such as font types and sizes, for different types of document components
when they are presented. As having a long adoption rate from specification
(CSS 1 : 1996, CSS 2 : 1998) to be fully supported by web browsers (2000 &
2006 for CSS2) it is predictable that CSS 3 modules like Backgrounds and
Colors, Media Queries, and Multi-column Layout will come in no short time
from now (2012), although many web sites today use CSS heavily. Through the
years, the need for high-level presentation objects like grids and common
layouts, leaded to the creation of CSS libraries called frameworks (
http://en.wikipedia.org/wiki/CSS_frameworks) to help web programmers in
composing more attractive web sites in a rapid way.

Technical Details

The objective is to complete an initial CSS framework in Smalltalk
(Phantasia http://www.squeaksource.com/Phantasia) with CSS Template
objects. Phantasia avoids to learn CSS syntax, and with proper completion
could obtain a rich object model of CSS objects beyond the specification
limits, suitable to edition through Smalltalk code. High-level template
objects could include navigational ones like lists, menus, or palettes,
useful in wizards. Presentational objects like template layouts, which are
already implemented by external CSS libraries like Blueprint, and scale to
whole CSS templates including reports, galleries, etc.

The model should be independent of web framework so it could be re-used in
Seaside, Aida, Iliad or other future web frameworks.

Benefits to the Student

The student will learn how to build and extend a model for a limited
textual technology (CSS), from the low level objects like CSS functions to
high level objects like Positioners. The student could apply the results of
his work to several popular Smalltalk web frameworks.

Benefits to the Community

The Smalltalk community working with web technologies will be tremendously
favoured by having ready-made CSS objects to incorporate easily in their
web applications.
