Thanks, for replying. This is sort of complicated because this is a drupal based website. The site is 3-columns that appear dynamically.
Yes, the rightnav is being used on some portions of the site. So based on the dynamic content generated by drupal, the #rightnav appears and the #leftnav is disabled.
The style “.siderbar-left Content” is for the 2column (left and center).
The style “#rightnav” appears when the left bar is dynamically disabled leaving a 2column layout (center and right).
Is there anyway I can use the solution you mention and specifically target IE7 only?
