An HTML element <body>can contain only block elements, such as <p>. If I declare an inline element like <span>be display: blockusing CSS, does the following HTML code work correctly?
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<title>Title</title>
</head>
<body>
<span style="display: block;">Hi!</span>
</body>
</html>
