A style is a group of formatting settings stored under a single name. Using styles and style sets rather than formatting ad hoc has several advantages:
The document looks professional and is easy to read.
Styles provide consistency and can apply several formatting properties at one time.
Heading styles can be used to create tables of contents and outlines.
If you change the formatting properties of a style, all instances of the style are updated with the formatting changes.
Word includes several built-in styles that cover most basic formatting needs in a document.
Click in the paragraph or select the text you want to apply a style to.
Click the Styles group dialog box launcher on the Home tab.
Alternatively, you can browse within the Styles gallery on the ribbon, which will also preview the formatting used in the style, but it's often easier to choose from all the available styles at once by clicking the dialog box launcher.
You can also create your own styles, saving a set of formatting to use easily in other places. If the need arises, creating a style is quick and easy. There are five different types of styles:
Character: Includes any type of character formatting, such as font size, type, color, and effects. These styles can be applied to any selected text.
Paragraph: Includes any type of paragraph formatting, such as paragraph, tab, border, and bullets and numbering formats. These styles will be applied to entire paragraphs.
Linked: Uses a combination of character and paragraph formatting properties. These styles will be applied to entire paragraphs as well.
Table: Provides a consistent style for all borders, shading, alignment and fonts in tables.
List: Applies similar alignment, numbering or bullet characters and fonts to lists.
You can also base a style on another style. The new style will inherit the formatting of the original style, as well as any changes made to the original style later.
Format the selected text the way you’d like it to appear in your style.
Click the New Style button, in the Styles pane.
The differences between the selected text that was formatted and the style that it’s based on will be captured. The style that it’s based on will also be listed here.
Give the new style a name.
Make any additional adjustments to the style formatting.
Basic formatting commands are found right in this dialog box. To customize more advanced formatting, click the Format button and select a category from the menu.
Click OK.
The new style is created and can be applied to other text in the document.
One of the benefits of using styles is that when you make a change to one, everything that's using the style is automatically updated.
Change the formatting of some text using a style.
Click that Style’s list arrow in the Styles pane.
To delete a style, select Delete or Revert to [style name]. If there is no option to delete the style, reverting it back to the style it was based on effectively deletes the style.
Select Update [style name] to Match Selection.
The style is updated, and the changes you made are applied to all text that uses the style.
There are a lot of built-in styles that don't get used and get in the way of the styles you're working with. You can change the Styles pane settings to show only the styles used in a document.
Click Options in the Styles pane.
The Style Pane Options dialog box opens.
Click the Select styles to show list arrow.
Select In use.
Click OK.
Now only the styles used in the document are shown in the Styles pane.
