The term nesting means to put one element inside the other.
Here is an example of nesting a p element inside a div element.
<div>
<p>This is nesting</p>
</div>
You see how the opening div tag comes first,
<div>
then the p tag
<p>This is nesting</p>
then the closing div tag
</div>
The same concept applies to this challenge.
opening anchor tag goes here
img element goes here
closing anchor tag goes here
Hope that helps!
