title: ASP.NET Web Forms: Master Page & CSS File
body: <p>I have a project (Web Application) that I need to implement with Web Forms. I have already prepared the design for the website and I will use one of the CSS templates that I already developed. In this case:</p>
  
  <ol>
  <li>Should I use a master page?</li>
  <li>Is there any relationship between the master page and the CSS file? If yes, how should I define master page with the CSS file? </li>
  </ol>
  
  <p>By the way, the CSS file is a ready template. </p>
