How to center div vertically inside of absolutely positioned parent div

Question

I am trying to get blue container in the middle of pink one, however seems vertical-align: middle; doesn\'t do the job in that case.

Answer 1

Here is simple way using Top object.

eg: If absolute element size is 60px.

.absolute-element { 
    position:absolute; 
    height:60px; 
    top: calc(50% - 60px);
}
