Remove blue border from css custom-styled button i

2019-01-01 04:55发布

I'm working on a web page, and I want custom-styled <button> tags. So with CSS, I said: border: none. Now it works perfectly in safari, but in chrome, when I click one of the buttons, it puts an annoying blue border around it. I thought button:active { outline: none } or button:focus { outline:none } would work, but neither do. Any ideas?

This is what it looks like before being clicked (and how I want it to still look after being clicked):

And this is the border I'm talking about:

enter image description here

Here is my CSS:

button.launch {
    background-color: #F9A300;
    border: none;
    height: 40px;
    padding: 5px 15px;
    color: #ffffff;
    font-size: 16px;
    font-weight: 300;
    margin-top: 10px;
    margin-right: 10px;
}

button.launch:hover {
    cursor: pointer;
    background-color: #FABD44;
}

button.change {
    background-color: #F88F00;
    border: none;
    height: 40px;
    padding: 5px 15px;
    color: #ffffff;
    font-size: 16px;
    font-weight: 300;
    margin-top: 10px;
    margin-right: 10px;
}

button.change:hover {
    cursor: pointer;
    background-color: #F89900;
}

button:active {
    outline: none;
    border: none;
}

Add this in your CSS file.

*{
  -webkit-tap-highlight-color: rgba(0, 0, 0, 0) !important;
}

This is an issue in the Chrome family and has been there forever.

A bug has been raised https://bugs.chromium.org/p/chromium/issues/detail?id=904208

It can be shown here: https://codepen.io/anon/pen/Jedvwj as soon as you add a border to anything button-like (say role="button" has been added to a tag for example) Chrome messes up and sets the focus state when you click with your mouse.

I highly recommend using this fix: https://github.com/wicg/focus-visible.

Just do the following

npm install --save focus-visible

Add the script to your html:

<script src="/node_modules/focus-visible/dist/focus-visible.min.js"></script>

or import into your main entry file if using webpack or something similar:

import 'focus-visible/dist/focus-visible.min';

then put this in your css file:

// hide the focus indicator if element receives focus via mouse, but show on keyboard focus (on tab).
.js-focus-visible :focus:not(.focus-visible) {
  outline: none;
}

// Define a strong focus indicator for keyboard focus.
// If you skip this then the browser's default focus indicator will display instead
// ideally use outline property for those users using windows high contrast mode
.js-focus-visible .focus-visible {
  outline: magenta auto 5px;
}

You can just set:

button:focus {outline:0;}

but if you have a large number of users, you're disadvantaging those who cannot use mice or those who just want to use their keyboard for speed.

In my instance of this problem I had to specify box-shadow: none

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

For anyone using Bootstrap and having this problem, they use :active:focus as well as just :active and :focus so you'll need:

element:active:focus {
    outline: 0;
}

Hopefully saved someone some time figuring that one out, banged my head for bit wondering why such a simple thing wasn't working.

If you want to delete same effect in input, you could add the following code as well as button.

input:focus {outline:0;}

Don't forget the !important declaration, for a better result

button:focus {outline:0 !important;}

A rule that has the !important property will always be applied no matter where that rule appears in the CSS document.
