How Style Relates to a Word 2007 Document
A style is nothing more than a collection of Word 2007’s formatting commands all stuffed into a single container. By combining various text and paragraph formats into a style, Word saves you a lot of time and effort.
Without styles, every time a part of your document — say, a main heading — needs to be formatted, you have to apply the same font, size, bold, paragraph-spacing, and other attributes again and again, every time it appears. That can be a pain.
With styles, you simply apply the style and Word applies all of these formats at once. And, if you change your mind, you can instantly update all the text formatted with the same style. Such is the beauty — and power — of the style.
All text in Word has a style. By default, Word uses the Normal style to format your text. Unless you specify otherwise, the Normal style is typically 11-point Calibri font, with left-aligned paragraphs, line spacing at 1.15, and no indenting.
