Infinitely sliding CSS3 gradient

问题

I have this simple animation that pulses back and forth diagonally, I would like it to slide endlessly instead of pulsing back and forth. Here is my code:

body {margin: 0; padding: 0;}

.error-con {
    background: rgba(255, 0, 89, 1);
    background: -moz-linear-gradient(45deg, rgba(255, 0, 89, 1) 0%, rgba(0, 179, 255, 1) 100%);
    background: -webkit-gradient(left bottom, right top, color-stop(0%, rgba(255, 0, 89, 1)), color-stop(100%, rgba(0, 179, 255, 1)));
    background: -webkit-linear-gradient(45deg, rgba(255, 0, 89, 1) 0%, rgba(0, 179, 255, 1) 100%);
    background: -o-linear-gradient(45deg, rgba(255, 0, 89, 1) 0%, rgba(0, 179, 255, 1) 100%);
    background: -ms-linear-gradient(45deg, rgba(255, 0, 89, 1) 0%, rgba(0, 179, 255, 1) 100%);
    background: linear-gradient(45deg, rgba(255, 0, 89, 1) 0%, rgba(0, 179, 255, 1) 100%);
    background-size: 400% 400%;
    -webkit-animation: errorBg 55s ease infinite;
    -moz-animation: errorBg 55s ease infinite;
    animation: errorBg 55s ease infinite;
    height: 100vh;
}

@-webkit-keyframes errorBg {
    0% {
        background-position: 93% 0%
    }
    50% {
        background-position: 0% 100%
    }
    100% {
        background-position: 93% 0%
    }
}

@-moz-keyframes errorBg {
    0% {
        background-position: 93% 0%
    }
    50% {
        background-position: 0% 100%
    }
    100% {
        background-position: 93% 0%
    }
}

@keyframes errorBg {
    0% {
        background-position: 93% 0%
    }
    50% {
        background-position: 0% 100%
    }
    100% {
        background-position: 93% 0%
    }
}

<div class="error-con"></div>

I tried removing the 50% keyframe but that just made the whole thing jump back to the start at the last keyframe. Any ideas?

The problem is your gradient. For an infinite loop you should have four colors:

background: -webkit-linear-gradient(45deg, rgba(255, 0, 89, 1) 0%, rgba(0, 179, 255, 1) 33%, rgba(255, 0, 89, 1) 66%, rgba(0, 179, 255, 1) 100%);
