HTML Checking for Large Sites
Rocket Validator automatically scans your sites for accessibility issues using the W3C Validator,
hosted on our own servers and integrated into our web crawler.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
The <script> tag allows authors to include dynamic scripts and data blocks in their documents. This tag accepts two optional attributes, type (which is unnecessary if it’s JavaScript, as that’s the default), and src to indicate the URL of the external script to use.
The language attribute is now obsolete and should not be used.

Rocket Validator checks HTML on your sites using the latest version of W3C Validator Nu HTML Checker, which is intended for HTML5 documents.
The page scanned is using an obsolete doctype, instead of the expected <!DOCTYPE html>.

The <font> element, used to define the font face, size and color in previous versions of HTML, is no longer valid in HTML5. Instead, you should rely on CSS styles.
For example, you can define a font size of 12px, bold text with inline styles like this:
<p style="font-size: 12px; font-weight: bold;">some text</p>

The default type for <script> tags is JavaScript, so you don’t need to include the type for JS resources.
In HTML5, there’s no need to specify the version attribute - it is now obsolete. Here’s an example minimal HTML document to start with:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Test</title>
</head>
<body>
<p></p>
</body>
</html>
