In the CMS, you have access to a WYSIWYG (What You See Is What You Get) tool bar which allows you to edit text just as you would in Microsoft Word. The pulldown menu (circled in red) are predefined styles for text. To use them, highlight the text you want to edit and choose the style from the menu.
The styles menu (circled in blue) is a way to create boxes and "pullouts" in your text.

An accordion is a way to presents lists to make it easy for people to scan the "headlines" and choose what they want. It's a great way to present a contact list of staff or a "Frequently Asked Questions" section.
Tabbed boxes are another way to present text or images in a scannable format. They are good at condensing related materials together in a way that lets the user scan through them looking for what they want. A good example is on the Corporate and Foundation Relations site.
Highlight boxes are a great way to draw attention to information outside of the main body text of a page. They are generally used in sidebars to house lists of related links or announcements, frequently accessed links or questions, or lists of staff members.
