height: 100% for <div> inside <div> with display: table-cell

set height: 100%; and overflow:auto; for div inside .cell

When you use % for setting heights or widths, always set the widths/heights of parent elements as well:

.table {
    display: table;
    height: 100%;
}

.cell {
    border: 2px solid black;
    vertical-align: top;
    display: table-cell;
    height: 100%;
}

.container {
    height: 100%;
    border: 2px solid green;
    -moz-box-sizing: border-box;
}

<div class="table">
    <div class="cell">
        <p>Text
        <p>Text
        <p>Text
        <p>Text
        <p>Text
        <p>Text
        <p>Text
        <p>Text
    </div>
    <div class="cell">
        <div class="container">Text</div>
    </div>
</div>

In Addition to jsFiddle, I can offer an ugly hack if you wish in order to make it cross-browser (IE11, Chrome, Firefox).

Instead of height:100%;, put height:1em; on the .cell.

table{
   height:1px;
}

table > td{
   height:100%;
}

table > td > .inner{
   height:100%;
}
