Making Simple Customizations
These customizations are all configuration options you can make through the Web.
The first and most useful place to look is the Plone control panel, which offers a variety of options for the site administrator. All the parts of a Plone site are designed to be easily changed and customized; the blue tabs you can see across the top of the page are easy to add and remove. Other examples are the boxes in the left and right columns, which are called portlets. Plone comes with several portlets, and you can easily choose where to display certain portlets.
CSS
affects everything in a Plone site. CSS determines all the
colors, all the positioning, and a lot of the images. If you have
the ability to change the CSS code, then you can change almost the
entire look and feel of your Plone site.
