CSS or Cascading Style Sheets are a language for describing the look and formatting of HTML elements in a webpage.
A concept used in systems design to describe the negative consequences of making seemingly innocuous design changes. Shorthand for a product's delayed but inevitable need to be reworked due to earlier, seemingly trivial decisions not having been fully thought through in the original release.
Designers incur this "debt" by making quick and easy choices that save time in the present but cause more complex problems later on down the road when it becomes necessary to change or add something.
The distance from the baseline to the top of a capital letter, number, or other upper-case glyphs.
A specific set of colours, usually with a limited number of values, chosen to suit the needs of a particular design.
A statistical method in which two variants of the same activity are compared against each other (typically with several variants), one at a time, and the most effective variant is selected.
Contrast in design can be accomplished by placing two opposite colours adjacent to one another, creating a focal point within the design that dominates the composition.
A type of serif, characterized by large x-heights and thick, blocky strokes with little variation in width.
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.
Commonly used to describe a 2D graphic that is made up of an organized grid of pixels, in other words, a bitmap.
An imaginary line on which most letters "sit". As such, it equals the height of an em square. The expected result of a baseline is to reference the height with which text is aligned. The alignment ranges from ascenders, which are the upper strokes in b, d, and h, down to descenders like j or y.
A data visualisation tool that can be used to explore and group people's thoughts or reactions to a set of concepts. Affinity diagrams are often used in user research and design thinking as an experimental technique for generating new ideas or solutions.
The emergent patterns in these visual representations can help identify which aspects your audience will respond well to, thus enabling decisions on the information architecture and next steps in the process.
It is important to note that affinity diagrams were initially developed for qualitative research but have since been adapted for quantitative research (though they are not typically used with statistical data).
