title: How to style the entire first row of a table in CSS
body: <p>I wanted to know if there's a way to style (background, text, hover effect) the entire first row of a table? I have tried a lot but nothing works. I tried this one too:</p>
  
  <pre><code>.category_table td{
  background: #000;
  color: #fff;
  font-weight: bold;}
  </code></pre>
  
  <p>but nothing works. Can somebody please help me out on this?</p>
