  <!--   <p class = 'title2'>Landgreen - fall 2017</p> -->

  <p class='center'>In this class we will learn to code by making projects centered around web development. We start with HTML and CSS, followed by JavaScript, our primary programming language. Next, we use JavaScript and the canvas element to render graphics. Finally,
    we will use libraries to integrate code written by other people into our own.
