The term Slot may refer to:

A slot is a container that can hold and manage dynamic items on the web. A slot can be populated with content using either an Add to Slot action or a renderer, and it may be configured as active or passive. A slot can also be used to hold a single item (a single snippet of HTML) or a collection of items (a page). It is often compared to an object or container, but differs in that it can be filled with multiple types of content at once and supports multiple values for the same attribute. A slot is an important component in the design of responsive websites.
