define alignment to buttons in advanced- xml

[harshal_chakran]

Hi,
I have used a code in advance xml for 3 buttons

<module name="HTML" layoutPanel="panel_row3_col1">
<param name="html"><![CDATA[
<h3>KPI Configuration Section</h3>
]]></param>
<module name="Button" >
<param name="label">button1</param>
</module>
<module name="Button" >
<param name="label">button2</param>
</module>
<module name="Button" >
<param name="label">button3</param>
</module>
</module>

But is get displayed as 3 button one below another. I want to them to be horizontally aligned, one being at left, other at center and one at right end.
Can anybody please help me with this. Is this also possible via CSS?

Add 'layoutPanel="panel_row3_col1_grp1"' to each Button module, changing the 'grp' number for each.
