Solution
It's like a hug.
Mom and dad (and sometimes uncle Rustem at the bus stop) hug their children (usually). Parents.

div embracing span. So div is the parent of span'have. And span — the daughter of his descendant.

span gave birth to an illegitimate daughter and called it the h1, in honor of her husband. Squeamish hugs.

For h1, span , a parent. Embrace through suffering.

Well the DIV is the parent for all that is in it... and that's all. In turn, the span of its subsidiaries, and h1 is a child of the span...
