title: HTML error checking? Need an extension or baked in?
body: <p>I noticed that my HTML is not getting validated in VSCode (I have the latest version). </p>
  
  <p>Here is a simple HTML code example:</p>
  
  <p><a href="https://i.stack.imgur.com/TV4US.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TV4US.png" alt="enter image description here"></a></p>
  
  <p>According to VSCode, no issues were found after saving the file as index.html. But, I have a misspelled <code>meta</code> tag element and a duplicate <code>body</code> tag.</p>
  
  <p>You can see that VSCode recognizes the file as being an HTML document.</p>

  <p>The VSCode official docs states that you can download an HTML extension to help with HTML formatting, but then I read that VSCode now includes a baked-in HTML formatter. There is also the popular <strong><em>HTML Snippets</em></strong> extension by <em>Mohamed Abusaid</em> that the docs recommend but, according to Mohamed, that extension is no longer supported because it conflicts with the <em>"existing VS Code HTML extension"</em>.</p>
  
  <p><strong>Question: What's the correct way to get my HTML validated ? Do I need an extension? Is there an internal setting somewhere? Thank you.</strong></p>
