What is the best way to eliminate the focus border using a vendor prefix?

I'm currently working on a responsive website using Bootstrap 4, but I'm struggling to remove all outlines when clickable elements are clicked. Despite my attempts with the following code snippet, it doesn't seem to work:

*,
*:focus {
   outline: none !important;
   -webkit-outline: none !important;
   -moz-outline: none !important;
   -ms-outline: none !important;
   -o-outline: none !important;
}

Since I do utilize borders in my design, I'd prefer not to use border: none.

Attached is a screenshot of how the site appears on my mobile device (iPhone XR) running Chrome: https://i.sstatic.net/ppCCs.jpg

Answer №1

Alright, to tackle this, we need to dive deeper into HTML and CSS. Bootstrap typically utilizes box-shadow to create this border-like effect.

To resolve this issue, you can override the existing box-shadow property that has been applied, and you should see positive results.

For instance:

/* Original CSS code from bootstrap */

.form-control:focus {
  color: #495057;
  background-color: #fff;
  border-color: #80bdff;
  outline: 0;
  box-shadow: 0 0 0 0.2rem rgba(0, 123, 255, .25);
}
<div class="input-group mb-3">
  <div class="input-group-prepend">
    <span class="input-group-text" id="basic-addon1">@</span>
  </div>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
</div>

If simply removing the box-shadow did not do the trick, feel free to reach out in a comment for further assistance.
