问题描述
我正在尝试将我的页面验证为HTML 5（W3c）。我有以下错误：这里不允许使用img元素（作为noscript元素的子元素）。当head的子元素时，noscript元素必须只包含以下子元素：link，style和meta。
I am trying to validate my page as HTML 5 (W3c). And I have the following error: The "img" element is not allowed here (as a child of the "noscript" element). The "noscript" element, when a child of "head", must contain only the following child elements: "link", "style", and "meta".
现场推荐我的代码：
将升级的代码段复制并粘贴到< head> ;以及< / head> ;在您要跟踪转化的网站的HTML代码中。例如，要跟踪注册，请将代码放在您的网站上'注册完成'网页。
On site https://developers.facebook.com/docs/ads-for-websites/conversion-pixel-code-migration recommendation for my code:"Copy and paste the upgraded code snippet between <head>; and </head>; in the HTML code of your website where you want to track conversions. For example, to track registrations, place the code on your 'registration completed' web page."
请参阅源代码：
<head>
<script type="text/javascript">
var fb_param = {};
fb_param.pixel_id = '1234567890';
fb_param.value = '10.00';
fb_param.currency = 'USD';
(function(){
var fpw = document.createElement('script');
fpw.async = true;
fpw.src = '//connect.facebook.net/en_US/fp.js';
var ref = document.getElementsByTagName('script')[0];
ref.parentNode.insertBefore(fpw, ref);
})();
</script>
<noscript><img height="1" width="1" alt="" style="display:none" src="https://www.facebook.com/offsite_event.php?id=1234567890&value=10.00¤cy=USD" /></noscript>
</head>
是否可以修改此代码并通过验证（在头部）？
Is it possible to modify this code and pass validation (in head section)?
推荐答案
W3C的HTML5规范定义了 这样的元素：
W3C’s HTML5 specification defines the content model of a noscript element in the head element like this:
如您所见，除了 link / <$ c之外，它不能包含任何其他内容$ c> style / meta 元素。所以不，在<$ c里面的 noscript 元素内修改任何东西都不可能允许 img $ c> head 元素。
As you can see, it cannot contain anything else than link/style/meta elements. So no, it’s not possible to modify anything to allow an img inside of a noscript element inside of the head element.
但是你可以在 img 里面code> noscript 如果你将 noscript 元素放在正文中，在这种情况下，内容模型是：
But you can have an img inside of noscript if you place the noscript element in the body, as the content model is in that case:
透明表示它与其父元素具有相同的内容模型。因此，例如，如果 noscript 位于 div 内，它可能包含的任何内容div 可能包含（除了另一个 noscript ）。
Transparent means that it has the same content model as its parent element. So for example, if the noscript is inside a div, it may contain anything that a div may contain (except of another noscript).
