Vexpo is short for Virtual Expo. This is a site coded by CodeRiver Studio to provide a virtual exhibition.
It consists of multiple Halls each containing multiple Stands.
All customisation of stands is done completely in the wordpress customizer, making it simple to setup and teardown exhibitions.
Halls and Stands are coded in in-line Scalable Vector Graphics (SVG) embedded with PHP code to allow full customisation and speedy loading.
