title: Do I have always use .css files?
body: <p>Are <code>.css</code> files always needed? Or may I have a <code>.css</code> "basic" file and define other style items inside the HTML page?</p>
  
  <p>Does <code>padding</code>, <code>borders</code> and so on always have to be defined in a <code>.css</code> file that is stored separately, or may I embed then into an HTML page?</p>
