JS-hiding the seekbar (but not the reset and play/pause buttons) - What is the "Id" of the seekbar object?

you can hide the seekbar (on timeline starts) with

document.getElementById("seek").classList.add("hidden");

and show the seekbar (on timeline ends) with

document.getElementById("seek").classList.remove("hidden");

• "hidden" is includes in the default css of storyline
• "hidden" much better than "display none", if you want to (re)show the hidden element later

important: if you have the storyline menu active, you has to add "show the seekbar" on the  timeline starts trigger of the Slide Master(s) of your course

on all used slide master: on timeline starts

document.getElementById("seek").classList.remove("hidden");

(If you use the trigger on the Slide Master, there is no need for "show seekbar" on timeline ends)
