html css 2 column layout, both columns same height automatically?

Question

I have a two column layout set up, and I want to have both columns automatically stretch to fill parent div of the two columns, The reason being that the left column has a background and border to it, and i want it to take up the entire side of the page so it won't look messy and such. I use inline-block to align the two columns, not float or anything (I can't use overflow:hidden because it messes up some of my features that may go out of the div, ex: dropdown menus) So I need to find a simple way to do this, using this method.

You can use CSS table layout (not HTML table layout, that would be poor semantics):

.container {
    display: table;
    table-layout: fixed;
    width: 944px;
    font-size: 0.75em;

}
.col {
    display: table-cell;
    vertical-align: top;
}

.container .left
{
    width: 236px;
    background-color:grey;
}
.container .right
{
    width: 708px;
    background-color:yellow;
}

<div class="container">
    <div class="col left">Left</div>
    <div class="col right">Right
    </br></br></br></br></br></br></br></br></br></br></br></br></br></br></br></br></br></br></br></br></br></br></br></br>Hey
      
    </div>
</div>
