title: How to easily apply Bootstrap to a completed ASP.net MVC 4 application?
body: <p>I created an ASP.net MVC 4 app. Now I decided to integrate bootstrap 3.0.3 in my app. But I found out it's not easy. I searched on google and found tutorials where they explain how to integrate bootstrap with a totally new ASP.net MVC app.</p>

  <p>My ASP.net MVC 4 app has 'Razor' as View engine and I selected the 'Internet Application' template. </p>
  
  <p>Do I have to modify all the views step-by-step because I didn't chose Bootstrap at the beginning?</p>
  
  <p>If I only include the bootstrap.css and bootstrap.js the pages become deformed.</p>
