A graphical representation of a user: usually a photo, illustration, or initial.

A small label, generally appearing inside or in close proximity to another larger interface component, representing a status, property, or some other metadata.

A list of links showing the location of the current page in the navigational hierarchy.

Buttons trigger an action such as submitting a form or showing/hiding an interface component.

A wrapper for multiple, related buttons.

A container for content representing a single entity. e.g. a contact, article, or task.

• when used alone, it gives a binary choice (checked/unchecked);
• in a group it allows the user to select multiple values from a list of options.

An input for choosing a color.

An input that behaves similarly to a select, with the addition of a free text input to filter options.

A means of inputting a date – often separated into multiple individual fields for day/month/year.

A visual way to choose a date using a calendar view.

A panel which slides out from the edge of the screen.

A menu in which options are hidden by default but can be shown by interacting with a button; it differs from a select in that it shows actions or navigation options and is not a form input.

A wrapper for related form fields.

A representation of a file such as an uploaded attachment or a downloadable PDF.

A link is a reference to a resource. This can be external (e.g. a different web page) or internal (e.g. a specific element in the current document).

Lists are used for grouping a collection of related items. In HTML there are three types:

• unordered list — for items in no particular order.
• ordered list — for items in a specific order.
• description list — for key-value pairs.

A modal is an interface element that appears over other content. It requires an interaction from the user before they can return to whatever is underneath.

A container for navigation links; these can be to other pages (e.g. main site navigation) or to elements within the current page (e.g. a table of contents).

Pagination is the process of splitting information over multiple pages instead of showing it all on a single page; also the name for the interface component used for navigating between these pages.

An element that pops up from another element over other content; it differs from a tooltip in that it is usually triggered via click instead of hover and can contain interactive elements.

A horizontal bar indicating the current completion status of a long-running task, usually updated continuously as the task progresses, instead of in discrete steps.

A representation of a user’s progress through a series of discrete steps.
