Theme Quick Start
Non-technical site administrators with limited knowledge of HTML should use the Theme Picker and Designer which is accessible from the Admin Bar. The Admin Bar displayed at the top of the page when viewed after logging in as a Site Administrator. (Hint: From the Page Designer, open any page for edit, then click the 'View' button to view the page as an Administrator. Click on 'Theme Designer' located on the left side of the screen to open the Theme Designer.)
The site's theme can be changed at any time but changes must be 'published' before they are activated. This provides protection in case something goes wrong. After publishing a change, a previously published theme can be restored.
