A seamless iframe makes it so that visitors are unable to distinguish between content within the iframe and content beside the iframe. Seamless.js is a jQuery library that makes working with iframes easy by doing all the seamless stuff for you automatically. Stuff like…
Automatically adds ‘seamless’ attributes to an iframe.
Easy communication between parent page and iframe page.
Auto-resizing the iframe to fit the contents of the child page.
Loading indicator when the child page is loading.
Auto failsafe to open iframe in separate window in case of error.
Inject CSS styles into the child pages.
Easily manage multiple iframes on the same page.
Allow the child page to pop out of the parent page.
