Hi Josie
Not sure if this is the right way but I did get it to work by enclosing the xpos in a div and giving it an id then adding this css to the theme css file
<div id="ptpromo">{$xmr_pos_2}</div>
then in skin/common_files/modules/TXS_XMenus_R/Menu theme/themeVariant.css
#ptpromo ul{
width:100%;
margin:0 auto;
text-align:center;
}
#ptpromo ul li a span{
color:#014d90;
}
However in the latest version of the site it's not working.
here it is working (The white menu with the same day dispatch etc)

Hope that's some help
