I use Ionic to control the slides (to "swipe", to set slide or to obtain the current slide) but the prolem doesn't regard it.
I've tried whit
$swipe and with pure js, the problem is the same.
When I swipe on the slide, I would like the indicator moved below the swipe (like in YouTube app), but the indicator moves slightly delayed.
I've do an example here with comments, I've made it with a yellow div to simule the swipe area and a red indicator. I've tested it with my smartphone.
In my example I move the indicator changing the margin-left.
How can I do the indicator more reactive? There is another method?
