Look and feel is a term used in descriptions of products and fields such as product design, marketing, branding and trademarking, to describe the main features of its appearance.
In software design, look and feel is used in respect of a graphical user interface and comprises aspects of its design, including elements such as colors, shapes, layout, and typefaces (the "look"), as well as the behavior of dynamic elements such as buttons, boxes, and menus (the "feel").

Look and feel is a term used in descriptions of products and fields such as product design, marketing, branding and trademarking, to describe the main features of its appearance.
In software design, look and feel is used in respect of a graphical user interface and comprises aspects of its design, including elements such as colors, shapes, layout, and typefaces (the "look"), as well as the behavior of dynamic elements such as buttons, boxes, and menus (the "feel"). Look and feel can also refer to aspects of an API, mostly to parts of an API which are not related to its functional properties. The term look and feel is used in reference to both software and websites.
Look and feel applies to other products. In documentation, for example, it refers to the graphical layout (document size, color, font, etc.) and the writing style. In the context of equipment, it refers to consistency in controls and displays across a product line.
Look and feel in operating system user interfaces serves two general purposes. First, it provides branding, helping to identify a set of products from one company. Second, it increases ease of use, since users will become familiar with how one product functions (looks, reads, etc.) and can translate their experience to other products with the same look and feel. Some companies try to assert copyright over their look and feel.
Apple Computer was notable for its use of the term look and feel in reference to their Mac OS operating system. The firm tried, with some success, to block other software developers from creating software which had a similar look and feel. Apple argued that they had a copyright claim on the look and feel of their software, and even went so far as to sue Microsoft, alleging that the Windows operating system was illegally copying their look and feel.
Although provoking a vehement reaction in the software community, and causing Richard Stallman to form the League for Programming Freedom, the expected landmark ruling never happened, as most of the issues were resolved based on a license that Apple had granted Microsoft for Windows 1.0. See: Apple v. Microsoft. The First Circuit Court of Appeals rejected a copyright claim on the feel of a user interface in Lotus v. Borland.
In widget toolkits
Contrary to operating system user interfaces, for which look and feel is a part of the product identification, Widget toolkits often allow users to specialize their application look and feel, by deriving the default look and feel of the toolkit, or by completely defining their own. This specialization can go from skinning (which only deals with the look, or visual appearance of the widgets) to completely specializing the way the user interacts with the software (that is, the feel).
The definition of the look and feel to associate with the application is often done at initialization, but some Widget toolkits, such as the Swing widget toolkit that is part of the Java API, allow users to change the look and feel at runtime (see Pluggable look and feel).
Some examples of Widget toolkits that support setting a specialized look and feel are:
- XUL (XML User Interface Language): The look and feel of the user interface can be specialized in a CSS file associated with the XUL definition files. Properties that can be specialized from the default are, for example, background or foreground colors of widgets, fonts, size of widgets, and so on.
- Swing supports specializing the look and feel of widgets by deriving from the default, another existing one, creating one from scratch, or beginning with J2SE 5.0, in an XML property file called synth (skinnable look and feel).
In APIs
An API, which is an interface to software which provides some sort of functionality, can also have a certain look and feel. Different parts of an API (e.g. different classes or packages) are often linked by common syntactic and semantic conventions (e.g. by the same asynchronous execution model, or by the same way object attributes are accessed). These elements are rendered either explicitly (i.e. are part of the syntax of the API), or implicitly (i.e. are part of the semantic of the API).
In Literature
In the novel Microserfs by Douglas Coupland, one of the characters owns two gerbils, named "Look" and "Feel".
