thanks thangavel

a simple solution use window.scrollto() after detecting top position of target element.

function goto(item) {    var top = document.getelementbyid(item).offsettop;    window.scrollto(0, top);  }
p {    height: 800px;  }
<button onclick="goto('one')">scrol element</button>  <p></p>  <div id="one">one element</div>

as alternative use jquery plugin "carousel". there many online, mine own version available here if interesting give try: https://github.com/gibbok/jquery-slidertv
