Customized Cesium Timeline with tracking


I now have the following scenario where I need to configure a customized timeline for the animation.
There are currently a few problems I cannot resolve.

  1. the CSS styling of the timeline. As you can see from the image, the current timeline is not intact, it is always missing something in the heading or at the end. Also, the timeline container is exceptionally long with a red straight line on the tick, which I want to get rid of.
  2. controlling the animation with the timeline. I tried to forward or rewind through the timeline tick but not working.

If there are any ideas, please let me know. Thanks in advance.
