Challenge: Uncomment HTML

Link to the challenge:

I am having challenge on the topic commenting and uncommenting
the result I get is telling me [no trailing comments tags should be visible on the page. →
please help me to understand it.

commenting is a way to communicate between me and you without the computer intervening

<!-- <h1> tailed comment </h1>-->
<!-- here is example --> 
<!-- ToDo: remove the useless comments -->
<!-- useless comment -->

because the computer doesn’t intervene with the comments. both of us can add whatever we want to the comments.

but what if there are useless comment we can delete it. or we can remove the trailing tags which are those <!-- -->

so giving my example above, if you wanna read my comments. you will find 2 are useless being there, so we untail the useful ones and delete the other.

<h1> untailed comment </h1>
here is example 

here is in detail article about commenting.
