an element uses css3"s rotate (), because ie8 does not support it, so the requirement hides this element in ie8 and displays it normally in other browsers. So use this style visibility: hidden 9; but no matter what version of IE it is, it hides the element (I just want to hide it in ie8), I want to ask, is there any other way to write it? what is the principle of 9? If there is any detailed article or explanation, please ask for advice
