title: If I built an app with a CSS framework, and then they change their styles, would the look of my site change with?
body: <p>Currently working on an app and am looking to rebuild the front end. These may be stupid questions but I am curious about the stability of these frameworks, a couple things in particular:</p>
  <ol>
  <li><p>As mentioned in the question, say one of these front end libraries were to update their UI components, would these changes reflect in my app or is it version dependent?</p>
  </li>
  <li><p>If for whatever reason one of these libraries were to cease to exist or cease to contribute, after having built an entire app around them, what would happen?</p>
  </li>
  </ol>
