Tips for eliminating borders in Bootstrap 4

Is there a way to remove the outline of a textbox in bootstrap 4? I've tried some solutions but they haven't worked. Any suggestions on how to achieve this?

https://i.sstatic.net/TOkmS.png

CSS

#content #main-content input[type=text]{
   border: 0;
   border: 1px solid #ccc;
   height: 40px;
   padding-left: 10px;
   outline: 0;
 }

html

<div class="form-group">
   <label for="title">Title <span>*</span></label>
   <input type="text" class="form-control" id="title" name="title" placeholder="Enter Title">
</div>
htmlcssbootstrap-4

Answer №1

To eliminate the focus outline, simply include the Bootstrap class shadow-none:

<div class="form-label-group">
  <input type="password" id="inputPassword" class="form-control shadow-none" placeholder="Password" required>
  <label for="inputPassword">Password</label>
</div>

Answer №2

The current theme applies a box-shadow of inset 0 -2px 0 #2196F3 when an element is in focus.

If you want to change this behavior without completely removing the shadow, you can use the following CSS code to maintain the same shadow effect when the element is focused:

textarea:focus, 
textarea.form-control:focus, 
input.form-control:focus, 
input[type=text]:focus, 
input[type=password]:focus, 
input[type=email]:focus, 
input[type=number]:focus, 
[type=text].form-control:focus, 
[type=password].form-control:focus, 
[type=email].form-control:focus, 
[type=tel].form-control:focus, 
[contenteditable].form-control:focus {
  box-shadow: inset 0 -1px 0 #ddd;
}

Ensure that you place this CSS code after both the Bootstrap CSS and the current theme's CSS for it to take effect.

Answer №3

While the solution provided may work, it may not be the optimal choice. One alternative approach is to customize the input/button outline by adjusting the variables. (Especially since the query is about using bootstrap 4)

If you decide to modify the Bootstrap 4 variables as shown here, you can apply the following code to eliminate all focus outlines:

$input-btn-focus-box-shadow: none;
$input-btn-focus-width: 0;

To only remove the button focus outline, you can use the following code:

$btn-focus-box-shadow: none;

This customization can also be extended to indicators, select, dropdown, etc. by referring to the default variables list of bootstrap 4

EDIT

This method is also applicable for v5: GitHub variables

Although disabling the focus outline is possible, it may not be recommended. Following web accessibility keyboard standards, a site should be navigable via tabbing. Disabling the CSS can hinder this functionality.

To cater to different user needs, a new pseudo class has been introduced: :focus-visible, which can be utilized, though compatibility across all platforms is not universal yet. Check out the Chromium changelog for more information

Answer №4

To get rid of the box-shadow when an input is focused, you need to add the following CSS code to your custom stylesheet after the bootstrap CSS to take precedence. It's recommended to use a custom parent class for better organization:

.custom-parent-class .form-group input[type=text]:focus,
.custom-parent-class .form-group [type=text].form-control:focus {
  box-shadow: none;
}

Answer №5

This code is an improvement and more concise:

input[type="text"], textarea {
              outline: none;
              box-shadow:none !important;
              border:1px solid #ccc !important;
                                                 }

Answer №6

One easy solution could look something like this:

form .form-control:focus{
  border-color: #0d6efd;
  box-shadow: none;
}

We are customizing the .form-control class from Bootstrap. I encountered the same problem and found a workaround that eliminates the need to worry about importing additional CSS files after Bootstrap. Note: #0d6efd represents the color I wanted to apply to my input field when it is selected.

Answer №7

When using a box-shadow, it's important to note that the outline in the button may not be completely hidden, and it won't work on inputs, text-boxes, and other form controls... However, utilizing the shadow-none property may result in a subtle and thin border, which is a preferable alternative to the previous solution. Here's the code snippet for reference:

<form action="/search" method="get">
  <center class="container">
    <div class="input-group mb-3">

      <input type="text" class="form-control shadow-none" placeholder="Search the web" aria-label="Username" aria-describedby="basic-addon1" required name="q" autocomplete="off">
      <input type="submit" class="btn input-group-text shadow-none" id="basic-addon1" value="search">
    </div>
  </center>
</form>

Answer №8

I recently tested the code below and it successfully worked for me. I hope that it can assist someone else as well.

.form-group input:focus{
     outline:0px !important; 
     box-shadow: none !important;
  }

Answer №9

For those who are customizing in SCSS

$input-btn-focus-box-shadow: none;

Answer №10

When using the @tao CSS style, this particular line proves effective:

However, the inset should ideally be set to zero. Otherwise, it may result in an unusual line appearing in the most recent version of Bootstrap 4.

<input type="radio" style="box-shadow: inset 0 0 0 #ddd;">

The use of 'shadow-none' is currently ineffective.

Answer №11

To remove the box shadow on focus, simply add the following CSS code: For instance,

.box_style:focus{
       border:none;
       box-shadow:none;
   }

Answer №12

Experiment with the !important declaration within your css styles. This can help prevent your styles from being overridden by others. Give this a try:

//style for regular text input fields
input[type=text]{
   border: 0 !important;
   height: 40px;
   padding-left: 10px;
   outline: 0 !important;
}
//style for selected/active text input fields
input[type=text]:focus{
   border: 0 !important;
   outline: 0 !important;
}
//style for hovered text input fields
input[type=text]:hover{
   border: 0 !important;
   outline: 0 !important;
}

Answer №13

After countless hours delving into developer tools to troubleshoot the recurring problem with Bootstrap 5.2 accordion buttons, which included attempting to define 

$accordion-button-focus-box-shadow: none
to no avail, I finally resolved the issue by implementing the following:

$accordion-button-focus-box-shadow: inset 0 -1px 0 var(--bs-border-color);

This approach mirrors tao's solution - adjusting the box-shadow to closely resemble the existing setting rather than disabling it completely - and integrates it into SASS for implementation at compile time instead of trying to override it in CSS.

Additionally, this modification is applied universally, making it significantly quicker and more efficient than individually setting shadow-none for each element with a box shadow.

Answer №14

Insert the following code for input: focus 

 -webkit-box-shadow: none;
box-shadow: none;
outline: -webkit-focus-ring-color auto 0px;
background-color: rgb(250,250,250);

Answer №15

Upon reviewing your css, it appears that you are toggling the border from 0 to 1. Below is a revised version:

#content #main-content input[type=text]{
 border: 1px solid #ccc;
 border: 0;
 height: 40px;
 padding-left: 10px;
 outline: 0;
}
