This snippet is a features for displaying two images and comparing them by dragging a slider. It is meant for use for example "before and after", or ""backstage and onstage", etc.
Just download the complete module and add it to your v8.0 addons folder. After restarting the server, update your module list and install the snippet. It will be then available in your snippet toolbar of the website builder.
This addon is based on the Zurb pluggin and has been developed and tested for Odoo v8.0. The screenshot shows the snippet with our custom Bloopark theme. It might look different if you have another theme installed. The styling is done in Less and compiled with Grunt. If you need help styling the snippet to your own needs please don't hesitate to contact us.
