how to apply css position:absolute correctly? - html

Question

the problem is div, called 'dragger_container' doen't behave as i expect, and gets out from the parent div. it is not acceptable, cause it's an element that shows user scroll progress (it's a jquery plugin mCustomScrollBar) and interacts with user.
ask anyone for help.
thanks in advance

You need to add position: relative to the parent container of dragger_container that you want it to be positioned within.
If you don't do this then dragger_container will be positioned absolutely to the nearest parent element that is relatively positioned, or if there isnt one then it will be positioned within body.
