<h2>Demo of goog.ui.Css3ButtonRenderer</h2>
<fieldset>
<legend>
These buttons were rendered using
<strong>goog.ui.Css3ButtonRenderer</strong>:
</legend>
<br/>
These buttons were created programmatically:<br/>
<div id="cb1"></div>
<br/>
These buttons were created by decorating some DIVs, and they dispatch
state transition events (watch the event log):<br/>
<div id="cb2">
<div id="foo" class="goog-css3-button" title="Title specified in HTML">
Decorated <b>Button</b>, yay!
</div><div id="bar" class="goog-css3-button goog-css3-button-disabled"
title="Initialized to DISABLED in HTML...">Decorated Disabled
</div><div id="fee" class="goog-css3-button">Another Button</div><div id="btn1"
class="goog-css3-button goog-css3-button-collapse-right">
Archive
</div><div id="btn2"
class="goog-css3-button goog-css3-button-collapse-right goog-css3-button-collapse-left">
Delete
</div><div id="btn3"
class="goog-css3-button goog-css3-button-collapse-left">
Report Spam
</div>
</div>
<br/>
Use these <strong>ToggleButton</strong>s to hide/show and enable/disable
the middle button:<br/>
<div id="toggleEnable" class="goog-css3-toggle-button"
title="Click here to enable/disable the button above">Enable</div>
<div id="hideShow"
class="goog-css3-toggle-button goog-css3-button-checked"
title="Click here to hide/show the button above">Show</div>
<br/><br/>
Combined toggle buttons<br/>
<div id="btn4" class="goog-css3-toggle-button goog-css3-button-collapse-right">
Bold
</div><div id="btn5" class="goog-css3-toggle-button goog-css3-button-collapse-right goog-css3-button-collapse-left">
Italics
</div><div id="btn6" class="goog-css3-toggle-button goog-css3-button-collapse-left goog-css3-button-checked">
Underlined
