What is white space? What is the difference between active and passive white space?

What will be an ideal response?

White spaces are the blank areas of a page, regardless of the color you choose to give them. Use white space deliberately in your design, rather than as an afterthought. Good use of white space guides the reader and defines the areas of your page. White space that is used deliberately is called active white space and is an integral part of your design because it structures and separates content. Sometimes the strongest part of a design is the active white space. White space is any area of the screen that does not include content, regardless of your background color. Passive white space includes the blank areas that border the screen or are the result of mismatched shapes.

Content presentation can become confused when designers do not use enough active white space to separate and define content. A lack of active white space creates the impression that a page contains too much information and that it will be difficult to find the piece of information you want. Plenty of active white space reduces clutter and clarifies the organization of your ideas.
