Quote::
Since setting the top and bottom margins to auto will give them zero height,
the only way to vertically center the element in this particular case would be to
set them both to 25% -- and event then, the box would be centered, not the content within it.
::End of quote
It turns out the box is not vertically centered by setting margin-top and margin-bottom to 25%.
Here is my test code, tested in firefox 48 and chrome 53.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>Html page</title>
<style>
div {
width: 500px;
height: 6em;
border: 3px solid black;
background: red;
}
p {
margin-bottom: 25%;
height: 50%;
margin-top: 25%;
background: green;
}
</style>
</head>
<body>
<div>
<p>Hello</p>
</div>
</body>
</html>

Now let’s consider an example where the margins of a list item, an unordered list, and a paragraph are all collapsed. In this case, the unordered list and paragraph are assigned negative margins:

I believe the author meant
Now let’s consider an example where the margins of a list item, an unordered list, and a header1 are all collapsed. In this case, the unordered list and header1 are assigned negative margins:
Note from the Author or Editor:
The text:
“Now let’s consider an example where the margins of a list item, an unordered list, and a paragraph are all collapsed. In this case, the unordered list and paragraph are assigned negative margins:”
…should instead be:
“Now let’s consider an example where the margins of a list item, an unordered list, and a heading are all collapsed. In this case, the unordered list and heading are assigned negative margins:” |
