title: How to format text cells in Jupyter?
body: <p>I would like to create a Jupyter notebook to make a tutorial.</p>
  
  <p>When I go to the jupyter website and I try jupyter in the browser, there is already a nice python tutorial, with some cells used as text explanations and others as code:</p>
  
  <p><a href="https://i.stack.imgur.com/uvR72.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/uvR72.png" alt="enter image description here"></a></p>
  
  <p>Now I create a new notebook and I am able to create different cells and format them in 4 types:</p>
  
  <ul>
  <li>Code</li>
  <li>Markdown</li>
  <li>Raw NBConvert</li>
  <li>Heading</li>
  </ul>
  
  <p>However none of them allow me to create the text explanations with white background as in the image above.
  I tried formatting one cell as markdown and it's just keeping with the grey background.</p>
  
  <p>Am I missing something? Thanks.</p>
