<p>Here you can select a theme. By selecting a theme, the theme details are stored in the session and applied to the template when rendering the resulting page.</p>

<p>Basically, the theme you select will do the following:</p>

<ul>
    <li>Remove all stylesheets previously defined in <code>config/theme.php</code>.</li>
    <li>Add classes to the <code>&lt;html&gt;</code> element, if defined.</li>
    <li>Add stylesheets as defined.</li>
</ul>

<p>You edit the settings for each theme in the configuration file <code>config/theme-selecotr.php</code>.</p>

<p>The view for the theme selector is in <code>view/theme-selector/index.tpl.php</code>. There is no need to edit this file.</p>

<p>The code that applies the details from session, to the template during rendering, is <code>config/routes/custom.php</code>. There is no need to change that file.</p>
