    <h2>Task 1: Lady Bug</h2>
    <p>Can you recreate the functions from the last lesson, but this time, connect them to the up/down/left/right arrow
      keys on your keyboard?</p>
    <p>The "down" function has already been completed for you.</p>

    <h3>Bonus Task: Add a "you win!" popup if the ladybug gets to the flower. Add a 'game over' popup if the ladybug
      bumps into the web.</h3>

    <h2>Key Takeaways</h2>
    <ul>
      <li>
        I can connect functions to keystrokes (e.g.: up, down, left, right).
      </li>
      <li>
        I use JavaScript to manipulate HTML.
      </li>
      <li>
        I can create more complicated if statements which depend on different variables.
