These layouts are CSS based and XHTML compliant. They come with a dwt file so can be edited in Microsoft Expression Web, Frontpage 2003 or Dreamweaver. You can alternatively use the HTML editor of your choice and ignore the dynamic template feature - we have some suggestions for free editors here. The integrated shopping cart software is the same for all the Ecommerce Plus versions. Following purchase you will receive a zip file which includes the design, shopping cart software, png files and the CSS based control panel for managing your store online.
If you prefer to use your own design with our shopping cart software then you may want to check out our Generic version. There is a developer license available if you plan on setting up multiple stores and we offer Responsive Designs that adapt to browser window size, device and orientation.
