What is Alignment?
Alignment is the design theory that builds order, and organization, and as a by-product of successful implementation, improves readability.
Alignment is a design principle that refers to the alignment of text or graphics on a page. While you probably won't notice when elements in a design are aligned, you will almost certainly notice when they are not. A design with poor alignment will look disorganized and incomplete.
Alignment is the design principle that creates order and organization and improves readability as a by-product of successful implementation. The effects of alignment are subtle but design can be the difference between a polished and unpolished design.
In literal terms, alignment means the arrangement of different items for different boundaries or edges of an acceptable area. Alignment is not much different from this in the graphics design definition. It means the lining of graphics and text with different sides of the design canvas.
