Did you know this is valid HTML?
<!DOCTYPE html> <title>My to-do list</title> <h1>My to-do list</h1> <p>Here are the things I need to do: <ul> <li>First item <li>Second item <li>Third item </ul> <p>That's it!
You can omit elements such as html, head, or body. Additionally, depending on the element, you can even omit the closing tag, like with p and li.
html
head
