Disabling border color for the hamburger icon in the navbar-toggler in Bootstrap with custom CSS

I've been struggling with this issue for a while now. I have searched and attempted various methods to remove the border color from the BS4 hamburger icon when it is clicked (it appears as Yellow on my local machine but in this snippet, it's blue).

Is there anyone who can assist me in resolving this? Any help would be greatly appreciated!

Below is the code snippet that I am working with: 

<nav class="navbar sticky-top navbar-expand-lg" style="background-color: #eeeeee">
  <button class="navbar-toggler ml-auto hidden-sm-up float-xs-right" type="button" data-toggle="collapse" data-target="#navbarToggler" aria-controls="navbarToggler" aria-expanded="false" aria-label="Toggle navigation">
    <span><i class="fa fa-navicon"></i></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarToggler">
    <ul class="navbar-nav ml-auto mt-2 mt-lg-0">
      <li class="nav-item active">
        <a class="nav-link active" routerLink="/about" routerLinkActive="active">
          <span>About</span>
        </a>
      </li>
      <li class="nav-item">
        <a class="nav-link" routerLink="/projects" routerLinkActive="active">
          <span>Projects</span>
        </a>
      </li>
      <li class="nav-item">
        <a class="nav-link" routerLink="/contact" routerLinkActive="active">
          <span>Contact</span>
        </a>
      </li>
    </ul>
  </div>
</nav>

Answer №1

This solution worked perfectly in my Bootstrap 4 project.

.navbar-toggler:focus,
.navbar-toggler:active,
.navbar-toggler-icon:focus {
    outline: none;
    box-shadow: none;
}

It is important to note: the outline serves a crucial purpose for accessibility, especially for individuals who rely on keyboards or have visual impairments. For more information, please visit and consider implementing alternative styling for the toggler when it's active or focused.

Answer №2

.menu-toggler,
.menu-toggler:focus,
.menu-toggler:active,
.menu-toggler-icon:focus {
    clear-outline: no;
    delete-border: null;
    conceal-shadow: off;
}

Answer №3

If you want to customize the border color of the burger icon in the Bootstrap navbar when it is clicked, you can do so by modifying the bootstrap.min.css file and locating the button:focus class. From there, you can either change the color or remove the outline entirely. Here's how:

button:focus {

outline: 1px dotted;
outline: 5px auto -webkit-focusring-color;

}

Answer №4

For Bootstrap, the navigation focus does not use border, but rather outline

To remove it, you can use:

button.navbar-toggler.ml-auto.hidden-sm-up.float-xs-right:focus {
    outline: none!important;
}

I hope this information is helpful :> 

button.navbar-toggler.ml-auto.hidden-sm-up.float-xs-right:focus {
    outline: none!important;
}
<nav class="navbar sticky-top navbar-expand-lg" style="background-color: #eeeeee">
  <button class="navbar-toggler ml-auto hidden-sm-up float-xs-right" type="button" data-toggle="collapse" data-target="#navbarToggler" aria-controls="navbarToggler" aria-expanded="false" aria-label="Toggle navigation">
    <span><i class="fa fa-navicon"></i></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarToggler">
    <ul class="navbar-nav ml-auto mt-2 mt-lg-0">
      <li class="nav-item active">
        <a class="nav-link active" routerLink="/about" routerLinkActive="active">
          <span>About</span>
        </a>
      </li>
      <li class="nav-item">
        <a class="nav-link" routerLink="/projects" routerLinkActive="active">
          <span>Projects</span>
        </a>
      </li>
      <li class="nav-item">
        <a class="nav-link" routerLink="/contact" routerLinkActive="active">
          <span>Contact</span>
        </a>
      </li>
    </ul>
  </div>
</nav>

Answer №5

This solution is effective for Bootstrap version 5.2:

.navbar-toggler {
  border: none;
  outline: none;

   &:focus,
   &:active,
   &-icon:focus {
     outline: none;
     box-shadow: none;
   }
}

Answer №6

When using Bootstrap v5.1.3:

.navbar-toggler:focus,
.navbar-toggler-icon:focus {
    Remove outline and box-shadow properties for better UI.
}

Answer №7

Solving the Dilemma in BS5:

Instead of piling on additional CSS classes to override Bootstrap styles, the recommended approach is to customize Bootstrap itself. For the current version, Bootstrap 5.2.3, there are two ways to achieve this:

(1) If you're using a SASS-generated Bootstrap, adjust these setting variables as follows:

$navbar-toggler-padding-y:          0;
$navbar-toggler-padding-x:          0;
$navbar-toggler-font-size:          1.5rem;
$navbar-toggler-border-radius:      0;
$navbar-toggler-focus-width:        0;
$navbar-toggler-transition:         none;

$navbar-light-toggler-border-color: none;
$navbar-dark-toggler-border-color:  none;

For more details on customizing Bootstrap via SASS variables, refer to this page.

Please note that customizing Bootstrap through SASS was also possible in BS4, but with potentially different variables.

(2) If you're working with static Bootstrap files and not SASS, you can still customize Bootstrap by tweaking the BS Setting CSS Variables:

Create a separate Bootstrap-CSS-Settings-File and include it AFTER the static Bootstrap-CSS-File in your HTML document. Define the variables you wish to modify here. Here's an example for changing variables for a specific element class:

.navbar {
  --bs-navbar-toggler-padding-y: 0;
  --bs-navbar-toggler-padding-x: 0;
  --bs-navbar-toggler-font-size: 1.5rem;
  --bs-navbar-toggler-border-color: none;
  --bs-navbar-toggler-border-radius: 0;
  --bs-navbar-toggler-focus-width: 0;
  --bs-navbar-toggler-transition: none;
  --bs-navbar-toggler-border-color: rgba(0, 0, 0, 0.1);
}
.navbar-dark {
  --bs-navbar-toggler-border-color: none;
}

It's worth noting that customizing Bootstrap through CSS Variables at a higher level was introduced in BS5. These variables may vary across different sub-versions, and the ones provided apply to version 5.2.3.

The initial query pertained to BS4, but information regarding BS5 customization has been included. This supplementary answer addresses the topic since search engines may display it even when inquiries relate to BS5 specifically.

Answer №8

.nav-toggle {
    border: none;
}

Success with this tweak

Answer №9

Give this a shot! It was successful for me.

.navbar-dark .navbar-toggler {
color: rgba(255, 255, 255, 0) !important;
border-color: rgba(255, 255, 255, 0) !important;
}

Answer №10

button:focus {
    no outline;
    no outline -webkit-focus-ring-color;
}

Answer №11

Below is my solution using SCSS (Sass) :

.navbar-toggler {
    &:focus,
    &:active {
      outline: none;
      box-shadow: none;
    }
  }

  .navbar-toggler-icon {
    background-image: none;
    
    &:focus {
      outline: none;
      box-shadow: none;
    }
  }
