PHP-eSeller has been updated to include fully responsive displays on the admin and public shopping cart displays so that they work well on all types of devices, mobile, tablets and desktop.
Some of the cart displays now use the JQuery Datatable system that can be easily modified to change formatting and add in other options.
The JQuery Datatable plugin is well documented, is very extensive and has many features and functions.
Other shopping cart displays are based on the latest version of Twitter Bootstrap which is a framework to ensure that displays work well on different device types. Bootstrap is a well known framework which can be easily changed and modified to work with your particular layout. It is also very well documented with many forum sites.
PHP-eSeller has been completely re-written and is fully compatible with PHP 7 servers.
