How to implement a sticky header on mobile devices

Question

I know how to implement a sticky header in a PC browser. However, on mobile devices, the scroll event behaves truly online. It only starts once after the window has stopped scrolling, so I cannot control "window.scrollTop" in real time.

I also tried position: sticky, but this was only supported on iOS8 and above.

So what is the right way to create a sticky title for mobile browsers? Any ideas appreciated, thanks ~

You can use a framework like bootstrap to easily achieve this. Here is a code snippet for it.

 <nav class="navbar navbar-default navbar-fixed-top">
      <div class="container">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
          </button>
          <a class="navbar-brand" href="#">Project name</a>
        </div>
        <div id="navbar" class="navbar-collapse collapse">
          <ul class="nav navbar-nav">
            <li class="active"><a href="#">Home</a></li>
            <li><a href="#about">About</a></li>
            <li><a href="#contact">Contact</a></li>
          </ul>
          <ul class="nav navbar-nav navbar-right">
            <li><a href="../navbar/">Default</a></li>
            <li><a href="../navbar-static-top/">Static top</a></li>
            <li class="active"><a href="./">Fixed top <span class="sr-only">(current)</span></a></li>
          </ul>
        </div><!--/.nav-collapse -->
      </div>
    </nav>
