 		<h3>Styling panels</h3>
 
-		<p>By default, panels have very simple styles to let you customize them as needed. Panels are essentially just simple blocks with no margins that sit on either side of the page content. The framework wraps the panel content in a <code>div</code> with class <code>ui-pannel-inner</code> which has a padding of 15 pixels. If needed you can override this with custom CSS or use option <code>classes.panelInner</code> to set a different class name for the <code>div</code>.</p>

 		<p>Panels have a fixed width of 17em (272 pixels) which is narrow enough to still show some of the page contents when open to make clicking out to close easy, and still looks good on wider tablet or desktop screens. The styles to set widths on panels are fairly complex but these can be overridden with CSS as needed.</p>

 		<p>Other than the theme background, width and 100% height styles, panels have very little styling on their own. The default theme for panels is "a". You can set a different theme for the panel by adding a <code>data-theme</code> to the panel container, or set <code>data-theme="none"</code> and add your own classes to style it as needed.</p>
