missing information:
a link to your site –
and/or the name and download link of your theme.
the changes will have to be done in style.css of the theme – adding a ‘border-left: 1px solid #000;’ or ‘border-right: 1px solid #000;’ to some of the styles.
but because most themes are different and use different div ids and classes to mark the sidebar and the center, you need to provide more information first.
hey thanks for the reply……..then site link is http://www.outsidervocals.com and the theme is FlexxTheme – Red. Here is the demo site link, it is an iThemes creation: http://flexxtheme.ithemes.com/red/
