<p><b>Disclaimer:</b> Due to a webkit bug involving pseudo classes and sibling selectors this may not work in some webkit-based browsers.</p>

<p>Here's our finished toggle button.</p>

<label id="label">
     <input type="checkbox" id="checkbox" />
     <span id="off">Off</span>
     <span id="on">On</span>
</label>

<p>Here's how we build it. First you start off with a label containing a checkbox and two spans.</p>

<label id="label">
    <input type="checkbox" />

    <span>Off</span>
    <span>On</span>
</label>

<p>Simple and not much to look at. Let's style those two spans to look like buttons and hide the checkbox.</p>

<label id="label">
    <input type="checkbox" id="checkbox" />
    <span id="off">Off</span>
    <span id="on" style="display:block;">On</span>
</label>

<p>Now, the key is to hide the "On" span initially with "display: none;". Then we show it when the checkbox is checked while hiding the "Off" span at the same time. This is done with this CSS:</p>

<pre>
#checkbox:checked + #off {
    display: none;
}
#checkbox:checked + #off + #on {
    display: block;
}
</pre>

<p>So, when the checkbox is checked we are targeting its sibling "off" and we are also targeting the sibling of the checkbox's sibling which is "on".</p>

<p>At this point you could use server-side code or javascript to react to the hidden checkbox being checked just like you would with a normal checkbox.</p>


p {
    margin: 10px;
}
pre {
    margin: 10px;
}

#label {
    cursor: pointer;
    display: block;
    margin: 20px auto;
    width: 200px;
}
#checkbox {
    display: none;
}
#checkbox:checked + #off {
    display: none;
}
#checkbox:checked + #off + #on {
    display: block;
}
#off {
