Hi Nandan,
I've got your need, so for do that you have to set your layout and customize the width though the CSS for each container.
If this will span the full width, you can overwrite this in the page specific CSS.
E.g. you can say that for displays which are more than 3000 pixels, you want the container width to be 2800:
@media (min-width: 3000px) {
.container{
width:2800px;
}}
Have a look of this documentation, it will be very useful for understanding the concept of Default Bootstrap Big Grid.
Please, remember to mark Correct or Helpful if you find my response useful.
Cheers
Alberto
