The principles of typography Theory as practice

Today we learned about The principles of type; back to basics applying the principles of typography its about how designers break up text into blocks and offer visual shortcuts that let users sift through masses of information making it easier to scan for information. 

what is typography?

Typography is the art and technique of arranging type to make written language legible, readable, and appealing when displayed. ... The term typography is also applied to the style, arrangement, and appearance of the letters, numbers, and symbols created by the process.

Serif typefaces are characterized by tiny lines (serifs) trailing from the edges of the strokes and stems. Also called "roman" typefaces, they are often used for headlines and narratives. Examples of serif typefaces include Georgia, Times New Roman, Palatino Linotype, Adobe Garamond Pro and Cambria.

Sans serif typefaces, on the other hand, lack these tiny lines. The French word sans means "without"—hence the name.

Alignment and Proximity

Alignment can both refer to how text is displayed (left to right, in most cases) and how each text block lines up with others. To align typographical elements more effectively, many designers rely on grid systems such as The 960 Grid System and the Golden Grid System.
