Change bootstrap navbar collapse breakpoint without using LESS

StackOverflow https://stackoverflow.com/questions/19827605

Question

Currently when the browser width drops below 768px, the navbar changes to collapsed mode. I want to change this width to 1000px so when the browser is below 1000px the navbar changes to collapsed mode. I want to do this without using LESS, I am using stylus not LESS.

My issue is the same as in this question: Bootstrap 3 Navbar Collapse

But all the answers in that questions explain how to do it by changing LESS variable. I haven't been dealing with LESS, I am using stylus so I want to know how this can be done using stylus or another method.

Thanks!

Solution 2

You have to write a specific media query for this, from your question, below 768px, the navbar will collapse, so apply it above 768px and below 1000px, just like that:

@media (min-width: 768px) and (max-width: 1000px) {
   .collapse {
       display: none !important;
   }
}

This will hide the navbar collapse until the default occurrence of the bootstrap unit. As the collapse class flips the inner assets inside navbar collapse will be automatically hidden, like wise you have to set your css as you desired design.

Bootstrap 4

Changing the navbar breakpoint is easier in Bootstrap 4 using the navbar-expand-* classes:

<nav class="navbar fixed-top navbar-expand-sm">..</nav>

  • navbar-expand-sm = mobile menu on xs screens <576px
  • navbar-expand-md = mobile menu on sm screens <768px
  • navbar-expand-lg = mobile menu on md screens <992px
  • navbar-expand-xl = mobile menu on lg screens <1200px
  • navbar-expand = never use mobile menu
  • (no expand class) = always use mobile menu

If you exclude navbar-expand-* the mobile menu will be used at all widths. Here's a demo of all 6 navbar states: Bootstrap 4 Navbar Example

You can also use a custom breakpoint (???px) by adding a little CSS. For example, here's 1300px..

@media (min-width: 1300px){
    .navbar-expand-custom {
        flex-direction: row;
        flex-wrap: nowrap;
        justify-content: flex-start;
    }
    .navbar-expand-custom .navbar-nav {
        flex-direction: row;
    }
    .navbar-expand-custom .dropdown-menu {
        position: absolute;
    }
    .navbar-expand-custom .nav-link {
        padding-right: .5rem;
        padding-left: .5rem;
    }
    .navbar-expand-custom > .container {
        flex-wrap: nowrap;
    }
    .navbar-expand-custom .navbar-collapse {
        display: flex!important;
        flex-basis: auto;
    }
    .navbar-expand-custom .navbar-toggler {
        display: none;
    }
}

**Bootstrap 3**

For Bootstrap 3.3.x, here is the working CSS to override the navbar breakpoint. Change 991px to the pixel dimension of the point at which you want the navbar to collapse...

@media (max-width: 991px) {
  .navbar-header {
      float: none;
  }
  .navbar-left,.navbar-right {
      float: none !important;
  }
  .navbar-toggle {
      display: block;
  }
  .navbar-collapse {
      border-top: 1px solid transparent;
      box-shadow: inset 0 1px 0 rgba(255,255,255,0.1);
  }
  .navbar-fixed-top {
      top: 0;
      border-width: 0 0 1px;
  }
  .navbar-collapse.collapse {
      display: none!important;
  }
  .navbar-nav {
      float: none!important;
      margin-top: 7.5px;
  }
  .navbar-nav>li {
      float: none;
  }
  .navbar-nav>li>a {
      padding-top: 10px;
      padding-bottom: 10px;
  }
  .collapse.in{
      display:block !important;
  }
}

Working example for 991px: http://www.bootply.com/j7XJuaE5v6
Working example for 1200px: https://www.codeply.com/go/VsYaOLzfb4 (with search form)

Note: The above works for anything over 768px. If you need to change it to less than 768px the example of less than 768px is here.

in bootstrap3, change this variable @grid-float-breakpoint to the one you need. The default value is 768px

Finally worked out how to change the collapse width by fiddling with '@grid-float-breakpoint' at http://getbootstrap.com/customize/.

Go to line 2923 in bootstrap.css(also min version) and change @media screen and (min-width: 768px) { to @media screen and (min-width: 1000px) {

So the code will end up being:

@media screen and (min-width: 1000px) {
  .navbar-brand {
    float: left;
    margin-right: 5px;
    margin-left: -15px;
  }
  .navbar-nav {
    float: left;
    margin-top: 0;
    margin-bottom: 0;
  }
  .navbar-nav > li {
    float: left;
  }
  .navbar-nav > li > a {
    border-radius: 0;
  }
  .navbar-nav.pull-right {
    float: right;
    width: auto;
  }
  .navbar-toggle {
    position: relative;
    top: auto;
    left: auto;
    display: none;
  }
  .nav-collapse.collapse {
    display: block !important;
    height: auto !important;
    overflow: visible !important;
  }
}

I just did this successfully by using the following CSS code.

@media(max-width:1000px)  {

    .navbar-collapse.collapse {
        display: none !important;
    }

    .navbar-collapse {
        overflow-x: visible !important;
    }

    .navbar-collapse.in {
      overflow-y: auto !important;
    }

    .collapse.in {
      display: block !important;
    }

}

In the Bootstrap 3 .LESS source code, there is a variable defined in variables.less called @grid-float-breakpoint which has the following helpful comment:

//**Point at which the navbar becomes uncollapsed
@grid-float-breakpoint: @screen-sm-min;

The matching @grid-float-breakpoint-max value is set to that minus 1px:

//**Point at which the navbar begins collapsing
@grid-float-breakpoint-max: (@grid-float-breakpoint-max - 1);

Solution:

So just set the @grid-float-breakpoint value to 1000px instead and rebuild bootstrap.less into bootstrap.css:

e.g.

@grid-float-breakpoint: 1000px;

The Sass way of changing bootstrap variables is actually documented on the bootstrap-sass github page.

Just redefine the variables before you @import bootstrap:

$grid-float-breakpoint: 1000px;

@import 'bootstrap';

In addition to @Skely answer, to make dropdown menus inside the navbar work, also add their classes to be overriden. Final code bellow:

    @media (min-width: 768px) and (max-width: 991px) {
        .navbar-nav .open .dropdown-menu {
            position: static;
            float: none;
            width: auto;
            margin-top: 0;
            background-color: transparent;
            border: 0;
            -webkit-box-shadow: none;
            box-shadow: none;
        }
        .navbar-nav .open .dropdown-menu > li > a {
            line-height: 20px;
        }
        .navbar-nav .open .dropdown-menu > li > a,
        .navbar-nav .open .dropdown-menu .dropdown-header {
            padding: 5px 15px 5px 25px;
        }
        .dropdown-menu > li > a {
            display: block;
            padding: 3px 20px;
            clear: both;
            font-weight: normal;
            line-height: 1.42857143;
            color: #333;
            white-space: nowrap;
        }
        .navbar-header {
            float: none;
        }
        .navbar-toggle {
            display: block;
        }
        .navbar-collapse {
            border-top: 1px solid transparent;
            box-shadow: inset 0 1px 0 rgba(255,255,255,0.1);
        }
        .navbar-collapse.collapse {
            display: none!important;
        }
        .navbar-nav {
            float: none!important;
            /*margin: 7.5px -15px;*/
            margin: 7.5px 50px 7.5px -15px
        }
        .navbar-nav>li {
            float: none;
        }
        .navbar-nav>li>a {
            padding-top: 10px;
            padding-bottom: 10px;
        }
        .navbar-text {
            float: none;
            margin: 15px 0;
        }
        /* since 3.1.0 */
        .navbar-collapse.collapse.in { 
            display: block!important;
        }
        .collapsing {
            overflow: hidden!important;
        }
    }

demo code

Navbars can utilize .navbar-toggler, .navbar-collapse, and .navbar-expand{-sm|-md|-lg|-xl} classes to change when their content collapses behind a button. In combination with other utilities, you can easily choose when to show or hide particular elements.

For navbars that never collapse, add the .navbar-expand class on the navbar. For navbars that always collapse, don’t add any .navbar-expand class.

For example :

<nav class="navbar navbar-expand-lg"></nav>

Mobile menu is showing in large screen.

Reference : https://getbootstrap.com/docs/4.0/components/navbar/

In bootstrap v4, the navigation can be collapsed sooner or later using different css classes

eg:

  • navbar-toggleable-sm
  • navbar-toggleable-md
  • navbar-toggleable-lg

With the button for the navigation:

  • hidden-sm-up
  • hidden-md-up
  • hidden-lg-up

This worked for me Bootstrap3

@media (min-width: 768px) {
    .navbar-header {
          float: none;
      }
      .navbar-toggle {
          display: block;
      }
      .navbar-collapse {
          border-top: 1px solid transparent;
          box-shadow: inset 0 1px 0 rgba(255, 255, 255, 0.1);
      }
      .navbar-collapse.collapse {
          display: none!important;
      }
      .navbar-collapse.collapse.in {
          display: block!important;
      }
      .navbar-nav {
          float: none!important;
          margin: 7.5px -15px;
      }
      .navbar-nav>li {
          float: none;
      }
      .navbar-nav>li>a {
          padding-top: 10px;
          padding-bottom: 10px;
      }
}

Took a while to figure these two out:

.navbar-collapse.collapse {
   display: none!important;
}
.navbar-collapse.collapse.in {
   display: block!important;
}

For Bootstrap 3.3 this is the only code you need:

@media (min-width: 768px) and (max-width: 1000px) {
   .navbar-collapse.collapse {
       display: none !important;
   }
   .navbar-toggle{
        display: block !important;
   }
   .navbar-header{
        float: none;
   }
}

Your best bet would be to use a port of the CSS processor you use.

I'm a big fan of SASS so I currently use https://github.com/thomas-mcdonald/bootstrap-sass

It looks like there's a fork for Stylus here: https://github.com/Acquisio/bootstrap-stylus

Otherwise, Search & Replace is your best friend right in the css version...

Hi i think you can do it using CSS like this you can change breakpoint bootstrap menu 

    @media (max-width: 1200px) {
    .navbar-header {
        float: none;
    }
    .navbar-left,.navbar-right {
        float: none !important;
    }
    .navbar-toggle {
        display: block;
    }

    .navbar-collapse.collapse {
        display: none!important;
    }
    .navbar-nav {
        float: none!important; 
    }
    .navbar-nav>li {
        float: none;
    } 
    .collapse.in{
        display:block !important;
    }
   .navbar-nav .open .dropdown-menu {
       position: static;
       float: none;
       width: auto;
       margin-top: 0;
       background-color: transparent;
       border: 0;
       -webkit-box-shadow: none;
       box-shadow: none;
    }
}

This is the working code for me. (Also the dropdown navbar links works)

@media (max-width: 1199px) {
  .navbar-nav {
    margin: 7.5px -15px;
 }
  .ul-links {
    display: block;
  }
  .navbar-nav>li>a {
    padding-top: 10px;
    padding-bottom: 10px;
    line-height: 20px;
  }  
  .navbar-header {
      float: none;
  }
  .navbar-left,.navbar-right {
      float: none !important;
  }
  .navbar-toggle {
      display: block;
  }

  .navbar-collapse.collapse {
      display: none!important;
      max-height: none;
  }
  .navbar-nav {
      float: none!important; 
  }
  .navbar-nav>li {
      float: none;
  } 
  .collapse.in{
      display:block !important;
  }
 .navbar-nav .open .dropdown-menu {
     position: static;
     float: none;
     width: auto;
     margin-top: 0;
     background-color: transparent;
     border: 0;
     -webkit-box-shadow: none;
     box-shadow: none;
  }
}

This is what did the trick for me:

@media only screen and (min-width:769px) and (max-width:1000px){
.navbar-collapse.collapse {
    display: none !important;
}
.navbar-collapse.collapse.in {
    display: block !important;
}
.navbar-header .collapse, .navbar-toggle {
    display:block !important;
}

In bootstrap 4, if you want to over-ride when navbar-expand-*, expands and collapses and shows and hides the hamburger (navbar-toggler) you have to find that style/definition in bootstrap.css, and redefine it in your own customstyle.css (or directly in bootstrap.css if you are so inclined).

Eg. I wanted the navbar-expand-lg to collapses and shows the navbar-toggler at 950px. In bootstrap.css I find:

@media (max-width: 991.98px) {
  .navbar-expand-lg > .container,
  .navbar-expand-lg > .container-fluid {
    padding-right: 0;
    padding-left: 0;
  }
}

And below that ... 

@media (min-width:992px) { 
    ... lots of styling ...
}

I copied both @media queries and stuck them in my style.css, then modified the size to fit my needs. I my case I wanted it to collapse at 950px. The @media queries must need to be different sizes (I'm guessing), so I set container max-width to 949.98px and used the 950px for the other @media query and so the following code was appended to my style.css. This was not easy to detangle from twisted solutions I found on Stackoverflow and elsewhere. Hope this helps.

@media (max-width: 949.98px) {
    .navbar-expand-lg > .container,
    .navbar-expand-lg > .container-fluid {
        padding-right: 0;
        padding-left: 0;
    }
}

@media (min-width: 950px) {
    .navbar-expand-lg {
        -webkit-box-orient: horizontal;
        -webkit-box-direction: normal;
        -ms-flex-flow: row nowrap;
        flex-flow: row nowrap;
        -webkit-box-pack: start;
        -ms-flex-pack: start;
        justify-content: flex-start;
    }
    .navbar-expand-lg .navbar-nav {
        -webkit-box-orient: horizontal;
        -webkit-box-direction: normal;
        -ms-flex-direction: row;
        flex-direction: row;
    }
    .navbar-expand-lg .navbar-nav .dropdown-menu {
        position: absolute;
    }
    .navbar-expand-lg .navbar-nav .dropdown-menu-right {
        right: 0;
        left: auto;
    }
    .navbar-expand-lg .navbar-nav .nav-link {
        padding-right: 0.5rem;
        padding-left: 0.5rem;
    }
    .navbar-expand-lg > .container,
    .navbar-expand-lg > .container-fluid {
        -ms-flex-wrap: nowrap;
        flex-wrap: nowrap;
    }
    .navbar-expand-lg .navbar-collapse {
        display: -webkit-box !important;
        display: -ms-flexbox !important;
        display: flex !important;
        -ms-flex-preferred-size: auto;
        flex-basis: auto;
    }
    .navbar-expand-lg .navbar-toggler {
        display: none;
    }
    .navbar-expand-lg .dropup .dropdown-menu {
        top: auto;
        bottom: 100%;
    }
}
