Quite often we want to leave a note in our code to explain what something does (especially if we are new to this). We can do this by writing comments.

Comments are tags that appear in our code but not on the webpage. This lets us write notes to ourselves about what some code means and what it does.

A comment looks like this:

<h1>Myrtle the Turtle</h1>
<!-- This is a comment to myself -->
<h2>Anatomy and Physiology</h2>

The above html looks like this when rendered:

The resulting webpage from the comment code snippet.

Add comments to your code to explain what each line of code does.
