Question

What is the method for creating a button that has a gradient background and no border, but is still the same size as a button that has a border (

My code is based on Bootstrap v4 and I am facing an issue with creating gradient backgrounds for primary buttons that also use outline. The challenge is to maintain the same height and width for both buttons without the 2px border on the primary buttons. Gradient borders are not supported, so I am seeking a solution to achieve this effect.

In the screenshot above, you can see the problem I am trying to solve. One workaround that I found effective in Chrome is:

  background-color: var(--background) !important;
  background-image: var(--gradient-background) !important;
  border-width: 2px !important;
  border-style: solid !important;
  border-image-source: var(--gradient-background) !important;
  border-image-slice: 1 !important;

This solution works perfectly in Chrome as shown here:

However, in Firefox, a strange bug occurs resulting in this:

Addtionally, setting the border color to transparent creates an undesirable effect at the edges in both browsers:

I have created a messy Codepen which demonstrates the issue with transparent borders: https://codepen.io/anon/pen/ymvYQX

Therefore, I seek assistance with either of the following options:

1) Resolving the Firefox bug to ensure consistent rendering across different browsers.

2) Exploring alternative solutions such as resizing the buttons or finding a better way to create gradient border lines.

Your help is greatly appreciated! Thank you.

To prevent the background from repeating, make sure to adjust the background-size property accordingly:

.btn-primary:not(:disabled):not(.disabled):active, .btn-primary:not(:disabled):not(.disabled).active, .show > .btn-primary.dropdown-toggle {

If you're looking to achieve a seamless design where borderless items align perfectly with bordered ones, a simple solution is to make use of a transparent border.

border-color: rgba(0,0,0,0);

To address any background issues, you can adjust the background image by manipulating both background-size and background-position.

For example:

button {
  background: linear-gradient(-60deg, #279DD9, #1169B2);
  border: 2px solid #000;
  width: 80px;
  background-size: 84px;
  background-position: -2px;
}

#b {
  border-color: rgba(0, 0, 0, 0);
}

<button id="a">Button 1</button>
<button id="b">Button 2</button>

To avoid hard coding any values, simply include background-origin: border-box;^reference in your CSS. This ensures that the background considers the border area as well. By default, it is set to padding-box, causing it to cover the padding area before repeating inside the border:

.btn-primary:not(:disabled):not(.disabled):active, .btn-primary:not(:disabled):not(.disabled).active, .show > .btn-primary.dropdown-toggle {
    color: #fff;
    background-color: #074c81;
    border-color: #074575;
}
.btn:not(:disabled):not(.disabled):active, .btn:not(:disabled):not(.disabled).active {
    box-shadow: inset 0 3px 5px rgba(0, 0, 0, 0.125);
}
/* remaining CSS code */

<div class="DrawerGroup_root___Kf5l">
  <button type="button" class="Button_root__2FLmr Button_gradientBackground__2z0L9 btn btn-primary">save</button>
  <button type="button" class="Button_root__2FLmr btn btn-outline-secondary">cancel</button>

</div>
