[SOLVED] How to create a CSS marquee effect without empty space

How to create a CSS marquee effect without empty space

The answers to How can I create a marquee effect? show how to create a marquee effect, but it leaves a lot of empty space at the end of each iteration of the marquee.

Is there a way to achieve a smooth <marquee></marquee> effect, using CSS, that doesn't have this empty space?

I have a lot of small elements, which look a bit like Stack Overflow's blue tags, that exclusively fill the content of the marquee, as opposed to one continuous body or a wall of text.

Solution

Here is a sample how you can do, and by setting the delay and duration you control the space between the texts

.marquee {
  background-color: #ddd;
  width: 500px;
  margin: 0 auto;
  overflow: hidden;
  white-space: nowrap;
}
.marquee span {
  display: inline-block;
  font-size: 20px;
  position: relative;
  left: 100%;
  animation: marquee 8s linear infinite;
}
.marquee:hover span {
  animation-play-state: paused;
}

.marquee span:nth-child(1) {
  animation-delay: 0s;
}
.marquee span:nth-child(2) {
  animation-delay: 0.8s;
}
.marquee span:nth-child(3) {
  animation-delay: 1.6s;
}
.marquee span:nth-child(4) {
  animation-delay: 2.4s;
}
.marquee span:nth-child(5) {
  animation-delay: 3.2s;
}

@keyframes marquee {
  0%   { left: 100%; }
  100% { left: -100%; }
}

<p class="marquee">
  <span>this is a</span>
  <span>simple marquee</span>
  <span>using css</span>
  <span>only tech</span>
  <span>with a delay</span>
</p>
