Twitter bootstrap: get rid of 1200px large display how?

Question

If you look at: http://twitter.github.com/bootstrap/scaffolding.html#responsive they have categories for nearly every device. I'd like to eliminate the last support device entry:

Large display   1200px and up   70px    30px

I'm a backend programmer, not a designer, so my css knowledge is limited. Can someone point me to the files I would need to modify in order to get rid of support for large display?

Thanks!

(PS if anyone is wondering why I would do this, it's corporate standard blah blah blah 1024px blah blah.)

Answer 1

There is no need to hack or update the bootstrap CSS files. You can disable the effects by restraining the container to grow further. Use:

.container-fluid,
.container {
  // Disable large-desktop breakpoint.
  max-width: $container-md;
}

The $container-md value is typically 970px, unless you changed the $grid-gutter-width. For LESS, replace the $ of variables with an @. For regular CSS, replace the variable with the hard coded pixel size.

Answer 2

If you are using the maxcdn version of bootstrap or just dont want to touch the source, just paste place the following css after loading the bootstrap stylesheet.

@media (min-width: 1200px) {
    .container,
    .navbar-static-top .container,
    .navbar-fixed-top .container,
    .navbar-fixed-bottom .container {
      width: 940px;
    }
    .row-fluid {
      width: 100%;
      *zoom: 1;
    }
    .row-fluid:before,
    .row-fluid:after {
      display: table;
      content: "";
      line-height: 0;
    }
    .row-fluid:after {
      clear: both;
    }
    .row-fluid [class*="span"] {
      display: block;
      width: 100%;
      min-height: 30px;

      *margin-left: 8.404255319148938%;
    }
}

Basically it enforces the 960px css for the 1200px.

Answer 3

Ok this wasn't that hard, starting on line 437 of bootstrap-responsive.css, remove this entire section:

@media (min-width: 1200px) {
...
}

Now just change this one line

@media (max-width: 979px) {

to this:

@media (min-width: 1200px) {

easy hack!

EDIT better explanation:

If you look at bootstrap-responsive.css, and you look at all the crap except the "Media Queries" you'd be left with basically the following outline:

/* Landscape phones and down */
  @media (max-width: 480px) { ... }

  /* Landscape phone to portrait tablet */
  @media (max-width: 767px) { ... }

  /* Portrait tablet to landscape and desktop */
  @media (min-width: 768px) and (max-width: 979px) { ... }

  /* Desktop */
  @media (max-width: 979px) { ... }

  /* Large desktop */
  @media (min-width: 1200px) { ... }

See how it gradually scales up? What I did is remove the last section, then changed the 2nd to last to take it's place.

EDIT:

BTW, if you use the boostrap customization wizard, you can do this on their GUI by unselecting large monitor support.

Answer 4

Best yet just remove:

@media (min-width: 1200px) { ... }

and it will only ever use the formatting for @media (max-width: 979px) for all desktop sizes

Answer 5

An alternative to this is setting the 1200px grid variables to those values for the regular grid values. With this method you can avoid updating the source and avoid upgrade issues:

@gridColumnWidth1200: 60px;

@gridGutterWidth1200: 20px;
