My css code is
#footer .right {
font-weight: bold;
color: #ffffff;
margin: 0px auto;
padding: 10px 0px 0px;
float: right;
}
and the text is
<p class="right">Copyright © 2012 SiteName. All Rights Reserved.<br />
Powered By ScriptName</p>
I need to set :
text font size (12px) for “Copyright © 2012 SiteName. All Rights Reserved.”
and text font size (11px) for “Powered By ScriptName”
It should be exactly look like that

How i can do that please ?
