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).
The area of negative space around and between elements in a design.
Red, green, and blue. These colours can be used to form a wide variety of colours in different devices such as computer monitors and televisions.
A graphic element that has a definite length and direction. Examples of vectors would be straight lines, edges, or curves.
The print resolution of a printer. It's a measure of how many dots per inch can be printed on paper. Higher DPI means more detail and smoother transitions between colours.
A software developer who designs, develops, maintains and supports the entire end-to-end product. These developers are capable of developing and implementing modern solutions to any industry problem.

A UX design technique in which you divide your users into groups, show them cards with different names for unrelated objects and ask them to categorise them.
A unit of measurement that equals 1/6 of an inch, or 1/72 of a foot.
The placement or otherwise of a thing in relation to other things. In design, proximity may be considered as the distance between two items in space or their relative location to each other.
The art of decorative writing practised by many different people in many different cultures. Calligraphy is sometimes used to add a personal touch to wedding invitations, special event invitations, and other projects.
A selector that can be applied to any HTML element. Classes should be used when designing for multiple instances. For example, if you want all <h1> tags in the website to look blue, then you could use the class="blue-text" attribute.
