title: HTML/PHP - Wrong closing tag order
body: <p>Of course, this tag is NOT correct :</p>
  
  <pre><code>&lt;b&gt;&lt;i&gt;Hi&lt;/b&gt;&lt;/i&gt;
  </code></pre>
  
  <p>However, it still runs perfectly in modern browsers (at least in newest version of chrome).</p>
  
  <p>What is the negative effect for this wrong order of code?</p>
  
  <p>Also, look at this :</p>
  
  <pre><code>&lt;table&gt;&lt;tr&gt;&lt;td&gt;Hi&lt;/td&gt;&lt;/table&gt;&lt;/tr&gt;
  </code></pre>
  
  <p>How will the browsers treat THIS code?</p>
