This worked for me on Chromium. The % for translate is in reference to the size of the bounding box of the element it is applied to so it perfectly gets the element to the lower right edge while not having to switch which property is used to specify it's location.
topleft {
top: 0%;
left: 0%;
}
bottomright {
top: 100%;
left: 100%;
-webkit-transform: translate(-100%,-100%);
}
