Gradient Borders

Gradient borders create modern, eye-catching effects. The generator handles the CSS complexity automatically:

/* Rainbow gradient border */

CSS equivalent (gradient borders require a workaround):
.gradient-border {
  border: 4px solid transparent;
  border-radius: 8px;
  background:
    linear-gradient(white, white) padding-box,
    linear-gradient(135deg, #ff0000, #ff7700, #ffff00, #00ff00, #0000ff, #8b00ff) border-box;
}

/* Brand gradient border */

    linear-gradient(white, white) padding-box,
    linear-gradient(135deg, #1a73e8, #34a853) border-box;
}

/* Animated gradient border */
@keyframes rotate-gradient {
  from { --angle: 0deg; }
  to   { --angle: 360deg; }
}
.animated-border {
  border: 3px solid transparent;
  background:
    linear-gradient(white, white) padding-box,
    conic-gradient(from var(--angle), #1a73e8, #ea4335, #fbbc04, #34a853, #1a73e8) border-box;
