title: Example of Selector grouping and Contextual Selector on CSS
body: <p>I'm going to have an exam tomorrow and I'm trying to understand the meaning and the answer of </p>
  
  <p>Selector grouping and Contextual Selector </p>
  
  <p>While I searched all around google with many sources it starts to make me confuse because when I answer this on my previous test I got the answer wrong when I used the answer that I found from the internet, but the one below is the correct answer from our professor.</p>
  
  <pre><code>a. Selector grouping example 
  
     td, th, li { property: value; }
  
  b. Contextual Selector example 
  
     table p { property: value; }   
  </code></pre>
  
  <p>Can anyone please give me some more information what does selector grouping and contextual selector mean with some more example please.</p>
