JPEG stands for Joint Photographic Expert Group, an international standards body that sets standards for creating and handling compressed digital images. The JPEG file format was designed to balance good visual quality and small file size, typically through lossy compression. The JPEG file format is widely used as a means of compressing digital images, particularly those produced by digital cameras.

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.

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.

A portion of an image where the remainder is discarded.

A graphic representation, such as an icon, of a company or brand. Pictorial marks can be used on marketing materials to communicate the intentions and personality of the company. Factors such as colour, placement, and shape are significant in how the general public perceives a pictorial mark.

A set of colors which can be used to create a particular visual effect. It is usually composed of multiple primary, secondary, and tertiary colours.

The distance between the baseline and the mean line of lowercase letters in a typeface. Nearby descenders (such as j) and ascenders (such as q) usually extend slightly below or above this height.

A philosophy that companies should take a user-centred approach to design, making sure they focus on the customer's needs and not on their company's needs. UX designers need to figure out what users want before building something and not after. They must also ask themselves if including "features" will provide any value to the product or service.

A type of typographical contrast used to convey emphasis. Italics were initially developed for the printing press and are now widely used in print, web design, public signs and labelling systems.

A tool that allows user experience designers, or people who design products and websites with consumers in mind, to track where users look on the screen. Eye-tracking can measure users’ attention and the duration of time they spend on different areas of a website. With this information, websites can create user experience solutions such as buttons with varying colours designed to catch the eye.
