Embedding refers to the process of integrating external content, like videos, maps, social media posts, or music, directly into a webpage or application. This is achieved using an embed code, typically an HTML snippet provided by the source of the content. Embedding allows for richer media experiences on websites, without hosting the content on the site's server. It’s especially useful for content like instructional videos, interactive maps, or social media feeds, enhancing the user experience and engagement without significantly impacting the site's performance.
