<div class="" style="word-wrap:break-word; line-break:after-white-space">I am generating a two-column document, and want to box in the statement of a theorem.
<div class="">If in one line, it runs across the two columns. So I put it in a \parbox, and broke it into two lines. </div>
<div class=""><br class="">
</div>
<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="">(and hence the frame) runs to the end of the column line. This makes sense, but it leaves</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>
<div class="">I don’t want to use rigid lengths (eg 4in) because the pdf that I generate will go through an ExplainEverything</div>
<div class="">recording, and I am not sure what the final dimensions of anything will be—I prefer to have that controlled</div>
