title: javascript not creating div
body: <p>For the past two hours I have been trying to generate a <code>div</code> with certain properties. However, each time I try, nothing happens. Please tell me what I am doing wrong.</p>
  
  <pre><code>function roundDivGenerator()
  {
  
  var roundDiv = document.createElement("div");
  
    roundDiv.id = "roundDiv" + gauballTracker;
    roundDiv.class = "roundDivClass";
    roundDiv.innerHtml = divTracker;
    document.getElementByTagName("body")[0].appendChild(roundDiv);
  
    var roundDivCss = document.getElementByClassName('roundDivClass').style;
  
      roundDivCss.height = "44px";
      roundDivCss.width = "44px";
      roundDivCss.backgroundColor = "#8ed066";
      roundDivCss.border = "#b0f2e6 3px solid";
      roundDivCss.borderRadius = "22px";
  
      roundDivTracker++;
  }
  round_Div_Generator();
  </code></pre>
