Hi...
finally I have find solution to set footer at bottom only on every page like in .css(using master page).
#content
{
clear:both;
width: 950px;
position:relative;
min-height:330px;
}
.footer
{
position:relative;
height: 5em;
margin-bottom:-5em;
background-image:url('bg_footer111.gif');
background-repeat:no-repeat;
font-family: Verdana, Arial, Helvetica, sans-serif;
font-size: 10px;
font-weight: bold;
color:#FFFFFF;
left:5px;
right:-5px;
width: 982px;
}
thank u.Its woring fine.
