What are styles?
Most people are used to writing documents according to physical attributes. For example, you might specify the font family, font size and weight (say, Helvetica 12pt, bold).
Styles are logical attributes. We use styles every day. For example, there are two styles of computers: desktop and laptop. Each has its own distinctive set of properties. You never say â€œmy computer is a low-weight, one-piece unit with an LCD screen attached to a rectangular casing containing the computing components and the keyboardâ€. Instead, you say â€œI have a laptopâ€.
OpenOffice.org styles are a way to do the same thing for your document. Using styles means that you stop saying â€œfont size 14pt, Times New Roman, bold, centeredâ€, and you start saying â€œtitleâ€. In other words, styles means that you shift the emphasis from what the text looks like, to what the text is.
