<div class="">My question is this:</div>
<div class="">(see attached example) if I set the width as either \linewidth or \columnwidth, the box </div>

<div class="">a lot of space to the right of the text in the box. </div>
<div class="">Is there a way to make the box fit the width of the text, rather than the predefined line or column width?</div>
