In this way, it will quickly return to its original position at the end of the animation, and it will alternate with the second set of pictures at this time. It will look like a set of pictures scrolling to the left in a continuous loop.

The specific steps are as follows:

1. Set two sets of the same pictures everywhere in the main body code

<nav>
  <ul>
<li>
  <img src="image/1.jpg" alt=""></li>
<li>
  <img src="image/2.jpg" alt=""></li>
<li>
  <img src="image/3.jpg" alt=""></li>
<li>
  <img src="image/4.jpg" alt=""></li>
<li>
  <img src="image/5.jpg" alt=""></li>
<li>
  <img src="image/6.jpg" alt=""></li>
  </ul>
</nav>
