Hi. Yes, that's true, although most of(if not 99%) implementations "out there" do it the bad way :/ Brice Parent gave another interesting idea, of using async="none|async|postponed|..." in loadable elements(such as images, object, video, iframe...) as an attribute, like <img src="photo.png" alt="photo!" postponed/> In this case, I believe we should discuss it with HTML list's people, right? Also, it would be really interesting to use as another background characteristic, as proposed by Sebastian Zartner. Like background-image: url(mygreatestphoto.jpg) postponed; or background-load-method: postponed; With that, we would even be able to say that: body.mobile div{ background-load-method: postponed; } this way, a server side application could write the body tag with or without the "mobile" class, therefore, all the div elements with background images would be postponed to load their background.
