<p>Sometimes, we just want to offer visitors simple variations of our website theme. Sometimes, we simply want to offer a stylesheet with improved accessbility. There are plugins that let you choose a different theme, but this plugin offers you to change only the stylesheet. In the admin settings, you can configure as many different stylesheets as you want. Those possibilities are offered in a list on the front page.</p>
<p>The list of available stylesheets can be shown in a dropdown list or as a series of icons. It can be shown using the widget or in a page/post using the shortcode, or directly in the template using the php function.</p>
<p>On the frontend, when a choice is made in the dropdown list, the webpage is reloaded using the chosen stylesheet.</p>

WP User Stylesheet Switcher

I'm using this on a site I'm developing that will have a "feminine style" and a "masculine style".  The site is in development so I didn't want to replace the default style.css as that would mean updating two stylesheets (ugh!).  Because the style switcher is loaded in the header after the main stylesheet, this is  what I did to cut down work ...

In the plugin I identified the default stylesheet as "Feminine Style" and entered a fake stylesheet name so it would never get replaced.  I then created a real "Masculine Style" and entered it's correct stylesheet name.  

This way the masculine overrides just the feminine styles I add to it to change :D  It works great.

Works Great
