lazyLoad
Currently, LazyLoad ( https://msdn.microsoft.com/en-us/ie/dn369270(v=vs.94) ) is implemented in IE and Edge, see support: https://caniuse.com/#feat=lazyload
However there is interest in standardization to enable developers lazy-loading images/iframes and other embedded content (and the proposed lazyLoad's attribute values differ from that of current Edge/IE implementation):
