Answer 1

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>
