Hi. I tried this(from w3c site):
<!DOCTYPE html>
<html>
<body>
<h1>My <span style="color:red">Important<div><p>block-level</p></div></span> Heading</h1>
</body>
</html>
About the browser..It show what is in block-level(int this case <div>), but i think that isn't correct because block-level starts on a new line and takes up the full width available while inline element no.
