HTML <slot> Tag

Description

The HTML <slot> tag is used in web development to define a placeholder within a web component where external content can be inserted. It is particularly useful when creating custom reusable web components, allowing developers to specify a designated location within the component where content from the DOM (Document Object Model) or other components can be dynamically added. This enables a more flexible and customizable approach to building web interfaces by allowing developers to slot content into predefined areas within their custom components, enhancing reusability and modularity in web development.
