Tranform rotate with degrees in the same rotation - css

Question

I am trying to rotate a cube with keyframes so it keeps rotating in the same direction with no rotation backwards and keeps rotating horizontally in one direction without reverse on infinite.
<div class="cube">
<div class="cube-face front"></div>
<div class="cube-face back"></div>
<div class="cube-face right"></div>
<div class="cube-face left"></div>
<div class="cube-face top"></div>
<div class="cube-face bottom"></div>
</div>
CSS degrees run over 360 and don't seem to stop... As you can see with the current keyframes the cube will rotate backwards, is there a solution to keep it going with CSS?
.cube {
width: 250px;
height: 250px;
position: relative;
transform-style: preserve-3d;
transform: rotateX(315deg) rotateY(-45deg);
animation: rotate-cube 5s infinite;
margin-bottom: 50px;
cursor: pointer;
}
.cube-face {
display: flex;
justify-content: center;
align-items: center;
position: absolute;
width: 250px;
height: 250px;
border: 2px solid black;
font-size: 90px !important;
font-weight: bold;
color: #000;
}
.cube .front {
background: #f15d2a;
transform: rotateY(0deg) translateZ(125px);
}
.cube .right {
background: #0063a6;
transform: rotateY(90deg) translateZ(125px);
}
.cube .back {
background: #ed1652;
transform: rotate(0deg) rotateY(180deg) translateZ(125px);
}
.cube .left {
background: #12b259;
transform: rotateX(0) rotateY(-90deg) translateZ(125px);
}
.cube .top {
background: #fff;
transform: rotateY(0deg) rotateX(90deg) translateZ(125px);
}
.cube .bottom {
background: #ffd54c;
transform: rotatey(90deg) rotateX(-90deg) translateZ(125px);
}
#keyframes rotate-cube {
0% {
transform: rotateX(315deg) rotateY(-45deg);
}
33.33% {
transform: rotateX(315deg) rotateY(-135deg);
}
66.66% {
transform: rotateX(315deg) rotateY(-225deg);
}
100% {
transform: rotateX(315deg) rotateY(-45deg);
}
}

Assuming you want the end and start to have the same rotation, you can set the final rotation to -405deg (360 + 45).
This should make sure the animation continues in the correct direction.
0% {
transform: rotateX(315deg) rotateY(-45deg);
}
33.33% {
transform: rotateX(315deg) rotateY(-135deg);
}
66.66% {
transform: rotateX(315deg) rotateY(-225deg);
}
100% {
transform: rotateX(315deg) rotateY(-405deg);
}
