如何为底部元素指定IE 11

Question

如何在css中指定IE 11？我有其他IE占了如下。

#teleport {

bottom: -230px;

bottom: -280px\9; /* IE 8 and below */

*bottom: -280px; /* IE 7 and below */

_bottom: -280px; /* IE 6 */

}

Answer 1

    _:-ms-fullscreen, :root .ie11up, #teleport { bottom: -280px; }

     @media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
   .ie10up, #teleport{bottom: -280px; }
}

问题解决了。
