Hi @rdellconsulting.
Thanks for your reply.
However the solution described in the post seems to applicable for 6 featured pages in two rows (same column width) while I am looking for 4 columns (adapting column width – using class span3 instead of span4) in one row.
Basically it seems that to achieve this I have to use a modified version of class-content-featured_pages.php but I don’t know how to do it with a child theme.
Any help would be much appreciated.
