问题
I'm working to create an infinite autoplay carousel based on the example here: https://codepen.io/jackoliver/pen/qVbQqW
Notice how smooth the codepen example is, it never jumps when the carousel resets from the last to first item.
Mine is less smooth - Mine is jumping on reset and I can't figure out why...
body {
align-items: center;
background: #E3E3E3;
display: flex;
height: 100vh;
justify-content: center;
}
@keyframes scroll {
0% {
transform: translateX(0);
}
100% {
transform: translateX(calc(-456px * 2));
}
}
.quotes-famous {
background: white;
box-shadow: 0 10px 20px -5px rgba(0, 0, 0, 0.125);
height: 500px;
margin: auto;
overflow: hidden;
position: relative;
width: 960px;
}
.quotes-famous::before, .quotes-famous::after {
background: linear-gradient(to right, white 0%, rgba(255, 255, 255, 0) 100%);

The codepen example doubles up on all the images (or quotes in your case).
