“Themes are among the most powerful features that can be used to
customize a web site, especially in Plone. Using custom themes can
help you brand your site for a particular corporate image; it
ensures standards compliance and creates easily navigable layouts.
But most Plone users still continue to use default themes as
developing and deploying themes that are flexible and easily
maintainable is not always straightforward.“We will first inspect a few structural changes and install
them, and then finally examine the various components and skin
layer items that have been changed, one at a time. Where restarting
Zope or rerunning your buildout would be required, this will be
noted.”
