Headings are a way to order the content in the body in relative importance:
- Most Important
- Very Important
- Important
- Less Important
- ... and so on.
You do this by using the heading tags.
Let's start with the <h1> tag which marks something as most important. For example, <h1>Most Important</h1>
Make the words 'Most Important' as more important than the other words in the body by using the h1 tag.
Surround the text on line 8 with <h1> and </h1>. Don't forget to close your tag!
