Text that is used to fill in a gap in a document.
A prediction model used in human-computer interaction. It states that the time required to move to a target area rapidly increases as the distance to the target increases. The law was proposed by Paul Fitts, an American psychologist, in 1954 as a mathematical model of movement with limited cognitive capacity.
Fitts hypothesized that one would quickly select its first apparent target when reaching for an object before considering alternatives — a phenomenon called "target fixation." This tendency would increase progressively with increased distance between the subject and object until it eventually became exponential (i.e., too far away).
A rule of thumb used in photography to create more visually appealing images which states that an image should be composed so that the subject or focus of the image occupies one-third of the picture space, with two equal vertical lines dividing their composition into two.
A type of design that features the strokes running predominantly from the upper left to the lower right.

The part of a letter, usually a vertical line, that rise above the x-height.
The art and science of arranging information so that it's intuitive to find, easy to navigate, presents a cohesive design, meets accessibility guidelines, looks attractive on any device or screen size and ultimately drives behaviour change.

The use of repeating elements and motifs for decorative purposes. In design, repetition occurs in many ways. It can be achieved by using a shape or design element in a pattern, and it can also be achieved through the use of multiple shapes or motifs that have similarities
A unit for defining the size of a font. It's not a distance; this unit's measurement is only relative to the typeface's design.
A design style first introduced by Microsoft Design Language based on minimalism and simplicity. This newer trend focuses on reducing nonsensical designs and makes the content more accessible for all users.
In this way of designing, fewer elements are used to create shapes and less emphasis on gradients and textures. This modern trend moves away from skeuomorphism. Instead, it focuses on a realistic view or illustration with buttons and icons appearing flat with no shadows.
Commonly used to describe a 2D graphic that is made up of an organized grid of pixels, in other words, a bitmap.
