The 'form-iframe' project primarily serves to display content from another source (which could be a web page or a video) in the current webpage without the need to navigate or redirect the user to that source. The content source is received through a property (src), and it is then displayed in an area that takes the full width and height of its containing element.
This project provides the user with functionality such as the ability to autoplay media, use their device's accelerometer and gyroscope, write to the clipboard, handle encrypted media data, picture-in-picture viewing, and web sharing. These features can greatly enhance the user's experience depending on the content.
One significant property is that the project allows fullscreen viewing, which can be of great use when viewing media that is best viewed in fullscreen mode, such as videos or interactive applications.
By using this project, the user can interact with diverse types of content that are served through an iframe, right in the current website, enhancing the browsing experience by providing seamless integration of external content.
