I am new to programming, just started with HTML recently, and as I was trying to create a sample website and checking it on validator.w3c it gave me the above error, and I am pretty sure that all the start and end tags are exactly the same count, can someone please help me with this, below is the code iam doing.

 <!DOCTYPE html>
    <html lang="en">
    <title>Pizza</title>
    <p><h1>My Favorite Pizza</h1></p>
    <p><h2>What is <em>Pizza</em>?</h2><a href="https://en.wikipedia.org/wiki/Pizza"></a>
    <p>a dish of Italian origin, consisting of a flat round base of dough baked with a topping of tomatoes and cheese, typically with added meat, fish, or vegetables.</p>

Try this code below. I have formatted it and fixed the errors you had.

<!DOCTYPE html>
<html lang="en">
  <head>
    <title>Pizza</title>
  </head>
  <body>
    <h1>My Favorite Pizza</h1>
    <h2>What is <em>Pizza</em>?</h2>
    <a href="https://en.wikipedia.org/wiki/Pizza"></a>
    <p>
      a dish of Italian origin, consisting of a flat round base of dough baked
      with a topping of tomatoes and cheese, typically with added meat, fish, or
      vegetables.

The errors in your code and how I fixed them:

  1. Your heading tags (h1, h2, etc) should not be nested inside <p> tags. In HTML, <p> means paragraph, and will make the font-size 16px, which you don't want in a heading. I have removed the <p> tags from all of your headings as they aren't supposed to be there.
  2. On line 24, you had the following code: <p><a href= https://www.instagram.com/pizzastation.eg/>Pizza Station</a></p>. Since you forgot to put the URL in quotation marks, it was considered a self closing tag because it had this format: <tag /> (a normal tag with a / after it), which is what self closing tags look like. Here are some examples: <br />, <meta />. I added quotation marks around the url so that it acts like a normal anchor tag.
  3. I put the <title> inside a <head> tag. The head tag should contain the following tags (if you're using them), not all of these are mandatory to have): <link>, <title>, <meta>, <style>, <script>, etc.

For others to view your website, you need to publish it to a web host. InfinityFree is a good one, but it could be a bit complicated for your first website. I would recommend W3Schools Spaces.

Good luck further learning HTML, you have started off well and are doing a good job :)
