<!DOCTYPE html>
<html lang="en">

    <style>
        #myElement {
            border:1px solid #CCC;
            width:100px;
            height:100px;
        }
    </style>
    <meta charset="utf-8">

    <div id="myElement" class="dummy" style="width:100px;height:100px;background:#CCC;">Hello World!</div>
    <br>

    <script>
    function printAttributes(){
        var element = document.getElementById("myElement");
        var attribs = element.attributes;
        console.log(attribs);
