On the frontpage, I have put in an article and embedded the content module for Hikashop. However, in the div layout, the images are overlapping. I would like only to have 3 on this home page, just spread out more.
That's because of the structure AROUND the listing module...
You have a table with two columns with a width of 50% each and the module is in one of them. So it can only take half of the available space. Fix your table in your article and it will be ok.
