Why wont .style.top = \"200px\"; work in this code? Calling the event within the element using oclick=\"this.style.left=\'200px\';\" doesn\'t work either.

        <button id="theButton">Do</button>
    </body>

<script type="text/javascript">
    document.getElementById("theButton").onclick = function(){
        document.getElementById("theDiv").style.top = "200px";
    };
</script>


To use a left or top style the element must be position:absolute, or position:relative, or position:fixed
