W3 Document Object Model Range offsets when having mixed content

Question

If I have a text element with a strong child element within its text. For example:

<p>abcd<strong>ef</strong>gh</p>

What would be the correct end offset value for a range that ends between g and h?

Answer 1

The range's endContainer property would be the text node whose content is "gh" and endOffset property 1.
