CSS background-size HTC is not valid in several cases

Using a compatible IE8 background-size HTC, if it is a display:block element, its background display is fine, but if the element display:none, then the background does not display, or, this element is a pseudo-element, does not display, Forced to rush the duration, do not use the background, directly add a picture element, everything OK
