Three Column layout

Note: Do not add multiple three-columns, only need to continue adding more columns to the existing three-column div

<div class="three-column">
    <div class="column">
        **content goes here**
    </div>
    <div class="column">
        **content goes here**
    </div>
    <div class="column">
        **content goes here**
    </div>
</div>
