Im here because other similar questions couldn\'t help my particular problem.
I need right div
to be 100% height all the time, where the parent
Make the right div position:absolute;
and make the parent div position:relative;
and then height:100%;
will work for the right div. Make sure you also adjust its x-position and width accordingly. In this example I gave it a left:50px
to make sure it appears to the right of the left column.
