Sounds like that is possible, per W3C am able to validate the following HTML code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Inline can another inline?</title>
</head>
<body>
<div>
<span>some text <span>comes here</span>.</span>
</div>
</body>
</html>
Is that means an inline can contain another inline? Am confused, so long I thought only block-level elements can contain another block-level or inline elements. Also thought inline elements can contain only text. Can any one give some theory here with W3C reference or some reference, please? Thanks.
