Dynamic Slider with Timeline Animation

Custom Animations with CSS Control Slide Transitions with the Timeline

The Timeline is a CSS animation that triggers a slide change upon completion. By default, it is a line at the top of the slider indicating the amount of time remaining until the slide changes. This option can also be used to create advanced animations within the slide. The default settings point to an element with the class ".compsoul-slide-timeline", but it must be remembered that this element must be unique and may not belong to the slider structure. For example, we can animate an element in the footer, and after the animation is complete, the slide will change in the header. The animation is turned off by changing the "timeline" property to "false".

Example of using animation based on default CSS styles:

.compsoul-slide-timeline:before {
  animation: compsoul-slide-timeline 6s linear forwards;
  animation-play-state: paused;
  background: #e7a14f;
  content: "";
  display: block;
  height: 100%;
  transform: translate(-100%, 0);
  width: 100%;
}

Editing animation parameters is done by changing the CSS settings. Based on the code presented, we can conclude that the transition time between slides is 6 seconds. It should be noted that the transition time should be longer than the slide change animation itself.

One of the most common mistakes made when implementing multiple modules on one page is failing to change the element responsible for slide animations and the element that listens to the appropriate CSS animation. For example, if two instances of the module have been installed on the page, you must set a separate element in each of them to control the timed slide change. Example below:

<script> 
  new Slider(".slider-first .compsoul-slide").options({
      timeline: ".slider-first .compsoul-slide-timeline"
  }).init();

  new Slider(".slider-second .compsoul-slide").options({
      timeline: ".slider-second .compsoul-slide-timeline"
  }).init();
</script>

Each instance of our module should contain a reference to the individual element responsible for changing the individual slides. Otherwise, the slide change will occur every time the animation of the element indicated in the default settings is completed.
