These buttons were rendered using

|
<strong>goog.ui.ImagelessButtonRenderer</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">
|
|
<!-- On FF2, if you don't enclose the contents of the button in a SPAN,
|
|
the bold element isn't rendered. Works on every other browser. -->
