I would like to create a rotate marquee,

CodePudding user response：

Define a slight larger width(here 150vw) than the screen and than translate from 0 to that extra width(150vw-100vw)

Also you can use a extra container and rotate it 6deg to remove a glitch kind of effect when animation restarts

body {
  overflow: hidden;
}

.roll {
  margin-top: 100px;
  width: 150vw;
  height: 50px;
  background-size: auto 100%;
  z-index: 2;
  position: relative;
  animation: scroll-left 2s linear infinite;
  color: #000;
  transform-origin: center center;
}

.roll1 {
  transform: rotate(6deg);
}

@keyframes scroll-left {
  0% {
    transform: translateX(0%);
  }
  100% {
    transform: translateX(-50vw);
  }
}
