Trying to make a dialog box in jquerymobile 1.4.5 a larger width. According to an example AND the directions on http://demos.jquerymobile.com/1.4.5/pages-dialog/ I think this should work (but it doesn't seem to). I copied their example and then overrode the .ui-dialog-contain attribute as documented. I'm using a Mac/Chrome to render the page. And I have seen this post before, but I can't get anyone's solution to work. I think some of that might be because of old versions of jquerymobile.
.ui-dialog-contain {
max-width: 200px;
}

<div role="main" class="ui-content">
<h1>Delete page?</h1>
<p>This is a regular page, styled as a dialog. To create a dialog, just link to a normal page and include a transition and <code>data-rel="dialog"</code> attribute.</p>
<a href="dialog/index.html" data-rel="back" class="ui-btn ui-shadow ui-corner-all ui-btn-a">Sounds good</a>
<a href="dialog/index.html" data-rel="back" class="ui-btn ui-shadow ui-corner-all ui-btn-a">Cancel</a>
