  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />

    <style type="text/css">
      .pink {
        width: 200px;
        height: 200px;
        background-color: pink;
      }
      .lightblue {
        width: 200px;
