8-9: Trim trailing blank lines.The extra blank lines at the end of the JSON file are harmless but unnecessary. Removing them keeps the config tidy and avoids spurious diffs later.

1-6: Sound rule selection – good starter set.The chosen rules cover the most common authoring mistakes and will surface useful feedback without being overly restrictive. Nice foundation.

🛠️ Refactor suggestion
Two complete HTML documents in one file – split or comment out.
Line 16 embeds a second <html> element directly after the first document’s closing tag. Browsers treat everything after the first root element unpredictably, and HTMLHint will report duplicate-ID issues if any appear. If you need both snippets, place each in its own file (e.g., test-bad.html and test-good.html) or wrap the second inside a comment.

In test.html at line 16, there is a second <html> element embedded directly
after the first document's closing tag, causing invalid HTML structure. To fix
this, either split the content into two separate HTML files or comment out the
second <html> element and its contents to avoid duplicate root elements and
potential duplicate-ID issues.

Document lacks DOCTYPE and several closing tags – HTMLHint will flag this.
Right now the first fragment violates every rule you just enabled:
- No
<!DOCTYPE html>before<html>→doctype-first. - Unclosed
<title>,<h1>,<p>,<a>,<li>tags →tag-pair. - Malformed
</ul(missing>) → parsing error.
Unless the goal is to demonstrate failing cases, consider fixing them so the file passes lint:
+<!DOCTYPE html>
<html>
<head>
- <title>Bad Page<title>
+ <title>Bad Page</title>
</head>
<body>
- <h1>Welcome
- <img src="image.jpg">
- <p>This paragraph is missing its closing tag
- <a href="about.html">About us
- <ul>
- <li>Item 1
- <li>Item 2
- </ul
+ <h1>Welcome</h1>
+ <img src="image.jpg" alt="Sample image">
+ <p>This paragraph is now properly closed.</p>
+ <a href="about.html">About us</a>
+ <ul>
+ <li>Item 1</li>
+ <li>Item 2</li>
+ </ul>

In test.html lines 1 to 15, the document is missing the <!DOCTYPE html>
declaration at the top, and several tags such as <title>, <h1>, <p>, <a>, and
<li> are not properly closed. Additionally, the closing </ul> tag is malformed
and missing the closing angle bracket. To fix this, add <!DOCTYPE html> before
the <html> tag, properly close all opened tags with their corresponding closing
tags, and correct the </ul> tag by adding the missing '>'. This will ensure the
HTML is well-formed and passes lint checks.
