Refactor GUI Stucture

[rocher]

Introduction

Gnoga GUI uses a grid view to distribute element of the User interface. This grid is made with table cells, which is inappropriate and not flexible. Modern HTML frameworks, like Bootstrap, provide much more flexible mechanisms to do the same job.

DoD — Gnoga grid view can optionally use div elements instead of table cells.

Tasks

• Change Gnoga to create grid views using div elements instead of cell tables
  • This requires to create a Pull Request in Gnoga repository
• Create new GUI structure using div elements and Bootstrap
