There is an error in the picture.

Either the HTML has an error or the tree has an error, but the grandchild of body with a parent of H1 does not match the HTML.

Thank you


If one studies the illustration closely, we see there are rounded corners which would indicate something other than a child element… A text node. Every element has one if it is not a void element. The text node is appended to the parent node more as a pseudo-child, not a grandchild of the parent’s parent.

I think I may have stated my point poorly.

The text inside of the H1 node states, “The heading”, though the text in the HTML says, “The title”. It is simply a typo it seems. One of them could be changed.

It’s not a typo. It’s a description.

I agree with this. It should be changed from “The heading” to “The title”.
