HTML Checking for Large Sites

Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.

Stray start tag “head”.

A start tag has been found in an unexpected place in the document structure. Check that the section appears before the section, and that is not duplicated.

The section of an HTML document is the container of metadata about the document, and must appear before the section. A common cause of this issue is duplicated sections.

Here is an example of a minimal HTML document structure:

 html> head> title>Testtitle> head> body> p>p> body> html>

Related W3C validator issues

Stray start tag “html”.

A stray start tag has been found in the document. As this tag defines the start of the whole HTML document, it should appear only once.

Stray start tag “script”.

A start tag has been found in an unexpected place in the document structure. Check that the section appears within the or sections.

Here’s an example of a script inserted in the head of the document:

 html> head> title>Testtitle> script> console.log("Hello from the head"); script> head> body> p>p> body> html>

Stray start tag “style”.

A start tag has been found in an unexpected place in the document structure. Check that the section appears within the section.

Although in general it’s better to put your styles in external stylesheets and apply them using elements, CSS styles can also be included inside a document using the tag. In this case, it should be placed within the section, like in this example:

 html> head> title>Testtitle> style> p style> head> body> p>This text will be green.p> body> html>

Bad start tag in “iframe” in “noscript” in “head”.

There is an iframe tag inside a noscript tag that is itself inside the head section of the HTML document. This is not allowed because an iframe cannot be nested inside the head section.

To fix this issue, you may move the noscript section that contains the iframe tag outside of the head section, and ensure that it is placed within the body section of the HTML document.

For example, this is invalid HTML because the head section cannot contain iframe elements:

 html lang="en"> head> title>My webpagetitle> noscript> p>Please enable JavaScript to view this websitep> iframe src="https://example.com/">iframe> noscript> head> body> body> html>

Moving the noscript inside the body section fixes the issue, as that’s where iframe elements belong:

 html lang="en"> head> title>My webpagetitle> head> body> noscript> p>Please enable JavaScript to view this websitep> iframe src="https://example.com/">iframe> noscript> body> html>

Element “head” is missing a required instance of child element “title”.

The section of an HTML document contains metadata about the document, and as a minimum it must include a tag defining the document title.

Common causes for this issue are forgetting to define the , or duplicated sections where one of them does not include the title.

Here’s an example of a minimal HTML document including the title:

 html> head> title>Don't panic! This is the titletitle> head> body> p>p> body> html>

End tag X did not match the name of the current open element Y.

And end tag has been found that does not match the current open element. Check the context to fix the start and end tags.

“meta” element between “head” and “body”.

tags, used for defining metadata about HTML documents, must appear within the . section, but it has been found out of place. Check the document structure to ensure there are no tags outside the head section.

A common cause of this issue is having a duplicated, out of place . section. Ensure that this section appears in its proper place and is the only container for tags.

Start tag “a” seen but an element of the same type was already open.

An tag can’t include other tags inside. Most probable cause is an unclosed tag, like in this example:

a href="one.html">Page 1 a href="two.html">Page 2a>

Start tag “button” seen but an element of the same type was already open.

A tag can’t include other tags inside. Most probable cause is an unclosed tag, like in this example:

button>Submit button>Cancelbutton>

Start tag “head” seen but an element of the same type was already open.

An opening tag has been found in an incorrect place. Check that there’s only a tag in the document.

This issue can happen because the expected closing tag was misspelled as , as in this example:

 html lang=""> head> title>Testtitle> head> body> body> html>

Or, it could happen because another . section was nested inside a previous one:

 html lang=""> head> title>Testtitle> head> head> head> body> body> html>

You’ve placed a lot of elements that belong in BODY in HEAD. All of this (I keep the closing HEAD tag).

The BODY tags aren’t mandatory to use. If they aren’t used they are implied. Same with the HEAD tags. When it sees the first A tag above the validator assumes there are both a closing tag for HEAD and a start tag for BODY before it. Then when it comes to the the end tag for HEAD and start tag for BODY you actually typed, it reports them as erroneous.

This may seem backwards, but the validator is just a machine. It takes it line for line. When it sees the A tag up in head it doesn’t see an error, because HEAD and BODY tags can be implied. The error exists first when it encounters your closing tag for HEAD. It’s often this way. The validator points out the point where the error i obvious to it, but the actual mistake can be much higher up in the HTML. One gets used to the validators way of «thinking» fairly quickly, because it’s actually logical, even if that can be hard to see when one is new to it.

Just place those links and the list where they belong and the errors will go away.

Stray end tag “X”.

An end tag for X has been found that does not correspond to a previous open tag. This usually happens when you close the same tag twice, for example:

ul> li>itemli> ul> ul>

End tag “a” violates nesting rules.

An end tag has been found to violate nesting rules. tags can’t include other tags inside. Most probable cause is an unclosed tag, like in this example:

a href="one.html">Page 1 a href="two.html">Page 2a>

End tag “code” violates nesting rules.

An end tag has been found violating nesting rules. Check other errors in the same document related to the element, and fix the unallowed nested elements.

End tag for “body” seen, but there were unclosed elements.

A closing tag has been found, but there are unclosed elements before it. For example this has an unclosed element:

body> section> body>

End tag X did not match the name of the current open element Y.

And end tag has been found that does not match the current open element. Check the context to fix the start and end tags.

Saw an end tag after “body” had been closed.

An end tag has been found after the closing tag, which breaks the expected HTML document structure.

Check out the document structure, a basic example follows:

 html lang=""> head> title>Testtitle> head> body> p>p> body> html>

Stray doctype.

All HTML documents must start with a (Document Type Declaration), that informs browsers about the type and version of HTML used to build the document. In HTML5, this is simply and must appear at the start of the document.

Here is an example of a minimal HTML document, including the Document Type Declaration at its start:

 html> head> title>Testtitle> head> body> p>p> body> html>

HTML Validation: Fatal Error

This HTML document is purposely invalid demonstrating the incorrect use of in the section. Validate this Document and View Source for more information.

Have you seen this error while validating your HTML documents? If so, you’ll want to correct this as soon as possible, it may be breaking the section of your documents.

  2. Error: Stray end tag .
  3. Error: Stray end tag .
  4. Error: Start tag seen but an element of the same type was already open.
  5. Fatal Error: Cannot recover after last error. Any further errors will be ignored.

The above shows the first error which is the in the . At the close of the the validator has terminated the and marks the and as stray end tags. Any other code that sits below the error in the is marked as an error due to the early termination of the element.

Facebook Pixel Code Breaks

If you are using the Facebook Pixel Code and have followed their instructions for inserting that code, you have this error in your section. If you have a class on your element, you’ll see the Fatal Error label. We haven’t figured out why, when the class attribute is added to the , that it invokes the Fatal Error Label from the validator.

How to Fix this Fatal Error

Move this part of the Facebook Pixel Code to the , you can place it right after the opening element. This also applies to any other invalid use of in the element e.g. .

What is the Element?

The element represents nothing if scripting is enabled, and represents its children if scripting is disabled. It is used to present different markup to user agents that support scripting and those that don’t support scripting, by affecting how the document is parsed.

John Mueller from Google states that it breaks everything within the .

Google Confirms Breaking Section Can Make hreflang Unrecognizable

Barry Schwartz from Search Engine Roundtable: “Google’s John Mueller said in a Google Hangout on Google+ last Friday that sometimes when href lang doesn’t get picked up, it might be that the header section of your HTML is broken. When that happens, Google can’t recognize that there is href lang code in there and doesn’t show any href lang errors to you because it is not apparent to Google that the code exists there.”

John Mueller from Google: “So it might just be that we don’t recognize the hreflang markup at all on those pages.

For example, what might happen is we can crawl and index those pages, but when we render those pages, something in the section of the pages is added early on, and that kind of breaks everything within the , which includes the hreflang markup.

So that might theoretically be happening. And if we can’t find the hreflang markup at all, we won’t flag it as an error, because we think there is nothing wrong with a page that doesn’t have hreflang .

So that might be something worth double checking. So what you can do there is open the page in a browser and use Inspect Element to see what the rendered view of the page actually looks like. And then double check to make sure that within the head section there is actually nothing like non-meta tag type that’s actually listed there.”

John Mueller from Google: 2018-03-28 “A somewhat niche technical issue I’ve seen recently is that some kinds of scripts (including some from Google) inject non-head HTML tags into the top of the head on a page. For us, this implicitly closes the head, and brings all of the meta-tags into the body of the page. For hreflang , that often results in those annotations being dropped completely. If you use hreflang , I’d double-check the rendered source with the Rich Results testing tool (it’s the only one that currently shows the rendered source), and check that there are no iframe’s or div’s above the hreflang annotations.”

    Consider validating your code. If your code passes validation, you’ve eliminated one potential issue in browser compatibility. With validated code, you won’t need to rely on each browsers’ error handling technique. There’s a greater chance that your code will function across different browsers, and it’s easier to debug potential problems.

    Write good, clean HTML. While your site may appear correctly in some browsers even if your HTML is not valid, there’s no guarantee that it will appear correctly in all browsers – or in all future browsers. The best way to make sure that your page looks the same in all browsers is to write your page using valid HTML and CSS, and then test it in as many browsers as possible. Clean, valid HTML is a good insurance policy, and using CSS separates presentation from content, and can help pages render and load faster.

    Dear JavaScript frameworks and plugins, if you could stop putting invalid tags in the HTML head, like IMG and DIV, that would be great.

    HTML and Debugging

    “HTML is not as complicated to understand as Rust. HTML is not compiled into a different form before the browser parses it and shows the result (it is interpreted, not compiled). And HTML’s element syntax is arguably a lot easier to understand than a «real programming language» like Rust, JavaScript, or Python. The way that browsers parse HTML is a lot more permissive than how programming languages are run, which is both a good and a bad thing.”

    “HTML itself doesn’t suffer from syntax errors because browsers parse it permissively, meaning that the page still displays even if there are syntax errors. Browsers have built-in rules to state how to interpret incorrectly written markup, so you’ll get something running, even if it is not what you expected. This, of course, can still be a problem!”
    Debugging HTML

    HTML Validation – Why Validate?

    “The core reason to run your HTML documents through a conformance checker is simple: To catch unintended mistakes – mistakes you might have otherwise missed – so that you can fix them. Beyond that, some document-conformance requirements (validity rules) in the HTML spec are there to help you and the users of your documents avoid certain kinds of potential problems.”

    “There are some markup cases defined as errors because they are potential problems for accessibility, usability, interoperability, security, or maintainability – or because they can result in poor performance, or that might cause your scripts to fail in ways that are hard to troubleshoot.”

    “Along with those, some markup cases are defined as errors because they can cause you to run into potential problems in HTML parsing and error-handling behavior – so that, say, you’d end up with some unintuitive, unexpected result in the DOM. Validating your documents alerts you to those potential problems.”

    Need Help with HTML Validation?

    I am very intimate with the HTML errors most websites generate and have validated over a million documents during my tenure (since 1995). I am available to assist Developers with validating their HTML documents at a minimal fee. Most validation routines can be handled in under an hour. Others may require multiple sessions. Either way, this is NOT rocket science and most Developers get IT after the first crash course consultation/validation routine at which time my services are no longer required. Contact me for more information.

    The reason for any “Cannot recover after last error” message you get from the validator is that in the backend we run the HTML parser in truly streaming mode. That’s for performance reasons, among other reasons.
