How to Customize Bootstrap Navbar Collapse Breakpoint Using Stylus

One common customization request for Bootstrap navbars is changing the breakpoint at which the navbar collapses. While Bootstrap 3 requires editing the LESS variables, this can be achieved in Stylus with some additional CSS.

Bootstrap 5

As of Bootstrap 5, managing the navbar collapse breakpoint has become simpler. By default, the navbar will collapse below 992px. You can customize this by adding the .navbar-expand-* class, where * represents the breakpoint you want to use:

• .navbar-expand-sm: Mobile menu below 576px
• .navbar-expand-md: Mobile menu below 768px
• .navbar-expand-lg: Mobile menu below 992px
• .navbar-expand-xl: Mobile menu below 1200px
• .navbar-expand: Navbar always expanded
• (No expand class): Navbar always collapsed

Bootstrap 4

In Bootstrap 4, you can use the same .navbar-expand-* classes as in Bootstrap 5. Additionally, you can create custom breakpoints using custom CSS:

@media (min-width: 1300px) {
  .navbar-expand-custom {
    // Custom CSS rules for navbar expansion
  }
}

Bootstrap 3

For Bootstrap 3, here's the working CSS:

@media (max-width: 991px) {
  // CSS rules to override the default collapse breakpoint
}

Replace 991px with your desired breakpoint. This will collapse the navbar below the specified pixel width.

Note for Breakpoints Below 768px
