    <h2>The Basic Concept</h2>
    <div class="section-text">
      <p>You control a turtle with a pen tied to its tail. As it moves across
        the screen, it draws the path that it follows. Change the turtle's
        speed, its pen's color, and more to create more complex drawings and
        animations.</p>
      <p>This simple mental model is all you need to draw
        all kinds of pictures!</p>

    <h2>Easy to Learn Graphics</h2>
    <div class="section-text">
      <p>We designed Turtle to be incredibly easy to learn and user friendly.
        We leverage the power of Rust's advanced type system to make using Turtle
        as convenient for you as possible.</p>

        <p>Use different colors, fills and other options to create anything you
          want! Turtle supports lots of different drawing commands so you can
          get really creative!</p>
