• Import the NgAnimatedBorderModule to your module.

• Add the ngAnimatedBorder directive to your [div, span, p, a, img] element.

• Add a background animation to your element. This animation will be the border animation.

<div ngAnimatedBorderWrapper>
    <span ngAnimatedBorder class="myCssAnimation">
        Magic
    </span>
</div>

.myCssAnimation {
    background: linear-gradient(270deg, #e922e9, #f75d21, #5543f7);
    background-size: 200% 200%;
    animation: borderAnimation 4s ease-in-out infinite;
}

@keyframes borderAnimation {
  0% { background-position: 0 50%; }
  50% { background-position: 100% 50%; }
  100% { background-position: 0 50%; }
}

Inputs

• The directive comes with different inputs.

[abBackgroundColor]

• sets the background color for your main element, since you dont want the animation affect your real background
• you can use any (s)css color value

abBackgroundColor: string = 'white';

[abBorderWidth]

• sets the borderWidth for: 1. all borders; 2: vertical, horizontal borders; 3: top, right, bottom, left border

abBorderWidth: [string] | [string, string] | [string, string, string, string] = ['1px'];

[abPauseAnimation]

Notes

• Not using the ngAnimatedBorderWrapper directive can lead to unintended results.
