old_contents: // DOM Manipulation Challenge
  
  
  // I worked on this challenge [by myself, with: ].
  
  
  // Add your JavaScript calls to this page:
  
  // Release 0:
  
  
  // Release 1:
  
  document.getElementById("release-0").className = "done";
  
  
  
  // Release 2:
  
  document.getElementById("release-1").style.display = "none";
  
  
  // Release 3:
  
  document.getElementsByTagName("h1")[0].innerHTML = "I completed Release 2";
  
  // example
  // document.getElementsByTagName("P")[0].innerHTML = "Hello World!";
  
  // Release 4: Add the background color #955251 to the #release-3 div. #955251 was Pantone's
  
  document.getElementById("release-3").style.backgroundColor = "#955251";
  
  
  // Release 5: Select all occurrences of class .release-4 and change the text-size to 2em.
  
  // METHOD 1: With a for loop
  // var x = document.getElementsByClassName("release-4")
  // var i;
  // for (i = 0; i < x.length; i++) {
  //     x[i].style.fontSize = "2em";
  // }
  
  // METHOD 2: by index
  var x = document.getElementsByClassName("release-4")[0].style.fontSize = "2em";
  var x = document.getElementsByClassName("release-4")[1].style.fontSize = "2em";
  
  // Release 6:
  var tmpl = document.getElementById('hidden');
  document.body.appendChild(tmpl.content.cloneNode(true));
  
  // Reflections:
  
  
  // QUESTION: What did you learn about the DOM?
  //   Answer:  I learned how to "grab" elements by their ID using
  //   the getElementById and getElementByClassName DOM commands.
  //   Using the name of the element and the index (which instance
  //   of that element for the case of a class that appears multiple
  //   times in the document) we were able to access and manipulate
  //   the HTML dynamically using JS.
  
  // QUESTIONS: What are some useful methods to use to manipulate the DOM?
  //   Answer:  The getElementById and getElementByClassName DOM
  //   commands as well as appendChild and getElementsByTagName were
  //   very useful as long as the .js file can be found by the html file.
