Bootstrap 3: How to set default grid to 960px width?

Question

I\'m working with Bootstrap 3 and the client wants the website container width to be set to 960px. Do I directly edit the CSS file or what is the best way to do this? I heard so

Answer 1

I wanted the max width to be 810px, so I used a media query like this:

@media (min-width: 811px) {    
    .container{
        width:810px;
    }
}
