Translate X and Y percentage values based on elements height and width?

Question

Translating an elements Y axis 50% will move it down 50% of its own height, not 50% of the parents height as I would expect. How do I tell a translating element to base it\'

You can also use one extra block and use the transition for it except the child node

css should be something like this

#parent {
    position: relative;
    width: 200px;
    height: 200px;
    background: #ff0;
}
#childrenWrapper{
    width: 100%;
    height: 100%;
}
#children {
    width: 10%;
    height: 10%;
    background: #f00;
}
