对，使用div去模似。<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<title> New Document </title>
<meta name="Generator" content="EditPlus">

<body>
<div id="tt" contenteditable="true"></div>
<script>
document.getElementById("tt").innerHTML = "<font color='red'>hello</font>说：<font color='blue' size=20>你好</font>";
</script>
</body>
</html>
使用div!!
