In this case a second problem may arise, -since the size of the delimiters will be chosen only for the -<strong>local part</strong>, so that the size of the <strong>visible</strong> -"left" and "right" delimiters might not match. -The solution is to trick LaTeX into thinking -that both parts have the same vertical height. This can be done by placing -a strut, that is a zero-width <a href="ltx-306.html"><tt>\rule</tt></a>. It -can also be accomplished with the <tt>\vphantom</tt> command, which I have -not found documented, but which appears to work. -<p> -<pre><tt>\vphantom{construct}</tt></pre> -creates a zero-width object with the height of <tt>construct</tt>.
