Bootstrap button - remove outline on Chrome OS X

问题

I am looking to achieve this: http://getbootstrap.com/javascript/#popovers-examples - scroll to the "live Demo" and hit the red popover button, in Chrome on OS X.... It's perfect beautiful

Now go here (the problem child): http://yoyo.io/javascript/#popovers - it outlines blue, aaaargh.

If you inspect you will see a litany of CSS efforts from me to remove this! It looks correct in Safari and Firefox but a no go in Chrome!

Anyone - what am I overlooking??

Many thanks in advance!

I see .btn:focus has an outline on it:

.btn:focus {
  outline: thin dotted;
  outline: 5px auto -webkit-focus-ring-color;
  outline-offset: -2px;
}

Try changing this to:

.btn:focus {
  outline: none;
}

Basically, look for any instances of outline on :focused elements — that's what's causing it.

For any googlers like me, where..

.btn:focus {
    outline: none;
}

still didn't work in Google Chrome, the following should completely remove any button glow.

.btn:focus,.btn:active:focus,.btn.active:focus,
.btn.focus,.btn:active.focus,.btn.active.focus {
    outline: none;
}

回答3:

.btn:focus, .btn:active:focus, .btn.active:focus{
    outline:none;
    box-shadow:none;
}

This should remove outline and box shadow

回答4:

In bootstrap 4 the outline is no longer used, but the box-shadow. If it is your case, just do the following:

.btn:focus {
    box-shadow: none;
}

回答5:

.btn.active or .btn.focus alone cannot override Bootstrap's styles. For default theme:

.btn.active.focus, .btn.active:focus,
.btn.focus, .btn:active.focus, 
.btn:active:focus, .btn:focus {
      outline: none;
}

回答6:

With scss:

$btn-focus-box-shadow: none!important;

回答7:

Search and replace

outline: thin dotted;
outline: 5px auto -webkit-focus-ring-color;

Replace to

outline: 0;

回答8:

This will remove it - short and clean:

.btn {
    outline: none !important;
}

回答9:

The simplest solution is: Create a CSS file and type this:

.btn:focus, .btn:active:focus, .btn.active:focus {
    box-shadow: none !important;
}

回答10:

Here's the solution:

#sec-one{padding: 15px 0;}
p{text-align: center;}
/*
* Change the color to any color you want;
* or set to none if you don't any outline at all.
*/
*:focus:not(a){
    outline: 2px solid #f90d0e !important;
    box-shadow: none !important;
}

<!doctype html>

            <input type="text" class="form-control" placeholder="Full Name" required>
          </fieldset>
           <fieldset class="form-group">
            <input type="email" class="form-control" placeholder="Email Address" required>
          </fieldset>
          <fieldset class="form-group">
            <input type="submit" class="btn btn-default" value="Sign Up">
          </fieldset>
          </form>
      </div>
    </div>
</div>
</section>
</body>
</html>

This works 100% hope it helps you.

回答11:

you can put this tag into your html.

<button class='btn btn-primary' onfocus='this.blur'>
     Button Text
</button>

I used on focus because onclick still displayed the glow for a microsecond and made a horrible looking flash in terms of using it. This seemed to get rid after all the css methods failed.

回答12:

That CSS goes from this file "tab-focus.less" in mixins folder (it could be difficult to find, because mixins are not shown at chrome dev-tools). So you should edit this:

// WebKit-style focus 

.tab-focus() {
      // Default
      outline: thin dotted;
      // WebKit
      outline: 5px auto -webkit-focus-ring-color;
      outline-offset: -2px;
    }

回答13:

In the mixins of the Bootstrap sources Sass files, remove all $border references (not in the outline variant).

@mixin button-variant($color, $background, $border){ 
$active-background: darken($background, 10%);
//$active-border: darken($border, 12%);    
  color: $color;
  background-color: $background;
  //border-color: $border;
  @include box-shadow($btn-box-shadow);
  [...]
}

Or simply code you own _customButton.scss mixin.

回答14:

If the above answers still do not work, add this:

button:focus{
    outline: none!important;
    box-shadow:none;
}

回答15:

If someone is using bootstrap sass note the code is on the _reboot.scss file like this:

button:focus {
  outline: 1px dotted;
  outline: 5px auto -webkit-focus-ring-color;
}

So if you want to keep the _reboot file I guess feel free to override with plain css instead of trying to look for a variable to change.
