I have recently tried and building a template with T3 BS3 but I have found that modules are not taking width automatically , they are not taking full width if I just assigned 1 module.
Example : If I assign a module say position-7 then within those spotlight row module should take 12 grid by default because there is only 1 module but it sticks to the position and takes 3 grid. I can do it via backend that but it will again assign to all pages.
I am looking for solution so modules can take automatically with according to the modules assigned within the row. Attaching example of how it looks when I just assign one module on site.
Looking forward to hear back with some solution. Let me know if I am missing anything.
