How to Format and Make a Style in Word 2013
Click the OK button to create the style.
The style is added to Word’s repertoire of styles for your document.
The style is created and it has also been applied to the paragraph you typed (in Step 1). You can now use the style, applying it to other paragraphs in the document.
The styles you create are available only to the document in which they’re created. They’re saved with the document, along with your text.
If you create scads of styles that you love and you want to use them for several documents, create a template.
You may have to tweak some settings in your style.
