Could someone clear what are the diffrence b/w /9 and /0 css hacks. I thought /9 is for late ie 10 browser and /0 for late ie-8. But i noticed /9 works for ie8-ie10 and /0 works for ie8 to ie11 browsers. This is quite strange to me.
div {
    width: 100px;
    height: 100px;
    border:#000 solid 1px;
    height: 300px\9;
    width: 300px\9;
    background: pink\0; 
}
i am looking at standard ie11 browser and its document mode.
