分享W3C 验证问题
下面代码不通过W3C验证 ( http://validator.w3.org/#validate_by_input ):
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>title</title>
</head>
<body>
<img src="img/test.png" width="116" height="215" />
</body>
</html>
提示错误:
Line 8, Column 51: required attribute "alt" not specified
<img src="img/test.png" width="116" height="215" />
The attribute given above is required for an element that you've used, but you have omitted it. For instance, in most HTML and XHTML document types the "type" attribute is required on the "script" element and the "alt" attribute is required for the "img" element.
Typical values for type are type="text/css" for <style> and type="text/javascript" for <script>.
--------------------------------
大家有什么建议吗? 我不明白这个错误. 如果去掉img这个节点, 就可以通过验证.

按信息提示，W3C要求图片的 alt 属性不能为空，必须填写，该属性是图片显示不出来时的代替文字...
