This chapter introduced you to the concept of a skin, or a set of styles applied to a piece of software. You then learned about all of the properties found in the Plone base_properties file and how they are used within the Plone standard style sheet. You learned how to add your own property, and you learned about the process for making a change in the base_properties that would have a rippling effect on the display of your site.
Additionally, the design process was briefly discussed so that you can understand the differences between creating a template for a static website and creating individual styles and elements that will fit into the Plone template. A good example of a Plone customization was shown, and you saw where standard Plone elements were customized to fit the goals of the example site.
In the next chapter, you'll learn about some varied topics, all related to working with content inside your Plone site. You'll learn about the underlying Plone templates, content syndication, and even how to create additional content types besides the common ones you've been using all along.
