Bootstrap 3 - remove breakpoint between md and lg

问题

I'm using Bootstrap 3 and trying to remove/exclude the breakpoint between medium and large devices. I have a existing website which is optimised to 970px which looks great. What I am trying to do is remove the md > lg breakpoint so that even on large widescreen desktops the maximum body width is 970px and still centred.

Anyone know if there is a quickfix solution to this?

Any advice would be much appreciated

If you're overriding the bootstrap breakpoint (and using containers properly), adding this below the bootstrap breakpoint media queries in the bootstrap CSS file should work for you.

If using LESS

@media (min-width: @screen-lg) { 
  .container {
      width: 970px;
   }
}

OR, you can simply override the bootstrap container in your own CSS (just make sure you load it after bootstrap.css)

@media (min-width: 970px) and (max-width: 2500px) {
   .container {
      width: 970px;
   }   
}

OR you can find the media query in the bootstrap.css file on around line 1240 and simply change it there

@media (min-width: 1200px) {
  .container {
     width: 1170px;  /* change 1170 to 970 */
  }
}

回答2:

the less way is good but this one is more flexible and reliable:

@media (min-width: @screen-sm) { .container { width:@screen-md; } }

Because in bootstraps default values the width of @screen-md is 992px. Now you will just have a breakpoint for small devices (smartphones) and any other bigger devices. they will all get the same layout

回答3:

You can set a max width on the containers:

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

No need for media queries or anything.

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.
