Everything between them is “commented out”. That means it’s there in the code but is “invisible” the browser - it has no effect on the web page, it doesn’t get used when building the page.
<p>A is for apple.</p>
<!--
<p>B is for ball.</p>
-->
<p>C is for ball.</p>
<!-- <p>D is for doll.</p> -->
<p>E is for elephant.</p>
If you were putting that into a web page, only the A, C, and E lines would show because the other two are commented out.
Why do you comment out?
To literally put comments, little notes to yourself or future programmers.
To temporarily hided code while you’re working on it, like if you want to see if a bug still shows up if this code were not there.
