Game Project Theme Redesign login, admin & main game theme

I’m looking to have the default theme replaced, I have example of how the new theme layout should look. It is a basic 2 col layout. I have attached what the existing layout looks like (img_0265) and what I would like the new theme to look like (animation.gif) the default layout uses bootstrap3 but the new theme would need to be bootstrap 4 or 5. I have also added a file with instructions how to set up for you to access the codes and see how it is structured. It needs to be mobile responsive also to which I will add mobile layout for you
