⚠️ Potential issue

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>
   </body>
 </html>

[error] 1-1: Doctype must be declared before any non-comment content.

(doctype-first)

[error] 3-3: Tag must be paired, missing: [ </title></title> ], start tag match failed [ <title> ] on line 3.

(tag-pair)

[error] 12-12: Tag must be paired, missing: [

], start tag match failed [
  • ] on line 12.

    (tag-pair)

    • 🤖 Prompt for AI Agents 
    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.

    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.

    [error] 16-16: Tag must be paired, missing: [ </h1> ], start tag match failed [ <h1> ] on line 16.

    (tag-pair)

    🤖 Prompt for AI Agents 
    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.
