I am trying to create a CSS theme switcher button like below. The top image shows what I have so far and the bottom image shows what I am trying to create.

I am not the best at this stuff I am more of a back-end coder. I could really use some help.

I have a live demo of the code here http://dabblet.com/gist/2230656

Just looking at what I have and the goal image, some differences.

• I need to add a gradient
• The border is not right on mine
• Radius is a little off
• Possibly some other stuff?

Also here is the code...it can be changed anyway to improve this, the naming and stuff could be improved I am sure but I can use any help I can get.

HTML

<div class="switch-wrapper">
    <div class="switcher left selected">
        <span id="left">....</span>
    </div>
    <div class="switcher right">
        <span id="right">....</span>
    </div>
</div>

CSS

/* begin button styles */

.switch-wrapper{
    width:400px;
    margin:220px;
}

.switcher {
    background:#507190;
    display: inline-block;
    max-width: 100%;
    box-shadow: 1px 1px 1px rgba(0,0,0,.3);
    position:relative;
