Would this be the correct use of indentation?

I keep reading about using indentation to make the code readable, in this particular exercise would this be the correct use of indentation?


  <h1>The Brown Bear</h1>
  <div id="introduction">
     <h2>About Brown Bears</h2>
     <h3>Species</h3>
     <h3>Features</h3>
  </div>

  <div id="habitat">
    <h2>Habitat</h2>
    <h3>Countries with Large Brown Bear Populations</h3>
    <h3>Countries with Small Brown Bear Populations</h3>
  </div>

  <div id="media">
    <h2>Media</h2>
  </div>

Does it make sense to you? What can you describe as the reason for this indentation?
