Making horizontal scroll with images infinite with no break CSS

Issue

I'm trying to make a logo portfolio carousel that scrolls horizontally in an infinite way.

I almost have it done, but it will break the animation and not be seamless. I need it to be really an infinite animation with no breaks.

body {
  margin: 0;
}

.scroll {
  position: relative;
  width: 100vw;
  background-color: $boxify-bg-light-dark;
  overflow: hidden;
  z-index: 1;
  margin: 0;
  padding: 0;
}

.m-scroll {
  overflow: hidden;
  height: 100%;
  white-space: nowrap;
  animation: scrollText 10s infinite linear;
  margin: 0;
  font-size: 0;
  display: flex;
  justify-content: space-between;
  width: 250%;
}

span {
  display: inline-block;
  margin: 0;
  padding: 0;
  color: white;
}

@keyframes scrollText {
  from {
    transform: translateX(0%);
  }
  to {
    transform: translateX(-50%);
  }
}

Solution

I don't quite understand the width 250vw setting. Try replacing it with width: fit-content. Then the -50% translate will translate the images to the right plaee.

[I assume that if you are showing different images you know to put a complete copy of them all into the HTML so the -50% works].

body {
  margin: 0;
}

.scroll {
  position: relative;
  width: 100vw;
  background-color: $boxify-bg-light-dark;
  overflow: hidden;
  z-index: 1;
  margin: 0;
  padding: 0;
}

.m-scroll {
  overflow: hidden;
  height: 100%;
  white-space: nowrap;
  animation: scrollText 10s infinite linear;
  margin: 0;
  font-size: 0;
  display: flex;
  justify-content: space-between;
  width: fit-content;
}

span {
  display: inline-block;
  margin: 0;
  padding: 0;
  color: white;
}

@keyframes scrollText {
  from {
    transform: translateX(0%);
  }
  to {
    transform: translateX(-50%);
  }
}
