The easiest way to make up a new style in Word 2016 is to format a single paragraph just the way you like. Once you've set text and paragraph formatting, follow these steps to create the new style:
Select the text you've formatted.
Click the Home tab.
In the Styles group, display the full Quick Styles Gallery.
Click the down-pointing arrow in the lower-right corner of the Gallery.
Choose the command Create a Style.
The Create New Style from Formatting dialog box appears.
In the Name box, type a short and descriptive name for your style.
For example, proposal body for the main text of a proposal or dialog for a character's lines in a play.
Click the OK button to create the style.
The style is created and applied to the selected text.
The style you create appears on the Ribbon, in the Style Gallery.
Styles you create are saved with the document, along with the text and other document info.
To make the style available to other documents, build a template. Styles in a template are available to all documents created by using that template.
You may have to tweak some settings in your style.
