A character style is a collection of character-formatting attributes that you can apply to a selected range of text. A paragraph style includes both character- and paragraph-formatting attributes, and can be applied to a selected paragraph or range of paragraphs. Using character and paragraph styles saves time and ensures consistent formatting.
You use the Character Styles and Paragraph Styles panels to create, apply, and manage character and paragraph styles. To apply a style, simply select text and click a style name in one of the panels. If you don’t select any text, the style applies to new text you create.
