通过JavaScript添加固定位置时，粘性div切换侧面

Question

I'm trying to implement a sticky div that is always present in the view when scrolling. My javascript code works fine, and the div is indeed scrolling with the page. The problem is when I apply position: fixed; to the my sticky div of class scrolling-panel , it switches position from the right of the page (the original position) to the left.

Here is my HTML (most relevant part, still a lot of markup though)

<div class="container">
    <div class="main-container">
        <div class="row">
            <div class="col-md-12">
                <img id="brand-logo" src="images/logo.png">
            </div>
        </div>
        <div class="row">
            <div class="col-md-12">
                <div id="container">
                    <img id='slider-img' src='images/img1.png'>
                    <div id='left_holder'><img onclick="slider(-1)" class='left' src="images/arrow_left.png"></div>
                    <div id='right_holder'><img onclick="slider(1)" class='right' src="images/arrow_right.png"></div>
                </div>
            </div>
        </div>
            <div class="scrolling-panel">

Javascript for the sticky scrolling-panel div:

$(document).ready(function() {
    var s = $(".scrolling-panel");
    var pos = s.position();
    $(window).scroll(function() {
      var windowpos = $(window).scrollTop();
          if (windowpos >= pos.top) {
              s.addClass("stick");
          } else {
              s.removeClass("stick");
            }
    });
});

Let me know if I haven't been clear enough and/or if you need more information

Answer 1

Instead of margin-right on the element (in .stick class) use a right value.

Here's a fiddle example
