You may want to jazz up a page with eye catching headings or use bold or italics to emphasis certain words. All of those options are available to you in the editor.

 

Headings&Styles

More Information:

There are six heading elements (h1 - h6). Google has recommended that each page have only one h1 heading. The title of each page is your h1. For example, for this page the h1 is "WordPress 101: Using Headings & Other Styles." With that in mind, you should only use h2 and below for your additional headings.
