我在使用w3c验证器对我的网站进行HTML5验证时遇到了问题。错误信息如下:
Bad value Content-Script-Type for attribute http-equiv on element meta
<meta http-equiv="Content-Script-Type" content="text/javascript" >
Bad value expires for attribute http-equiv on element meta
<meta http-equiv="expires" content="Wed, 26 Feb 1997 08:21:57 GMT" >
Bad value pragma for attribute http-equiv on element meta
<meta http-equiv="pragma" content="no-cache" >
Bad value Cache-Control for attribute http-equiv on element meta.
<meta http-equiv="Cache-Control" content="no-cache" >
如何正确设置 meta 标签以通过 HTML5 验证器?
