title: Where is the width of a slick.js slide calculated?
body: <p>I have tried using the slick initial setting 'variableWidth: true', but then the carousel container (.slick-track) is set to 20000px wide and does not respond to screen width, so then the width of each slide is not responsive either. <strong>So, to be clear, 'variableWidth: true' is not useful to me.</strong></p>
  
  <p>I have seen the questions here:</p>
  
  <p><a href="https://stackoverflow.com/questions/23273506/how-can-i-change-the-width-and-height-of-slides-on-slick-carousel">How can I change the width and height of slides on Slick Carousel?</a>  </p>
  
  <p>and here:  </p>
  
  <p><a href="https://stackoverflow.com/questions/25775152/fixed-width-slides-with-slick-carousel">fixed width slides with slick carousel</a>  </p>
  
  <p>but I do not want to set the width of each slide as a fixed pixel amount; They need to be responsive.  </p>
  
  <p>I'd really like to know where the width of a slide is calculated, when 'variableWidth' is left at the default of 'false'; The carousel is <strong>very</strong> close to looking correct (each slide just needs to be slightly wider). I've been looking through the slick.js plugin but cannot find a reference to 'width' that is applied as css.  </p>
  
  <p>There are several references to 'px' in the plugin, but these are to do with either padding or position.  </p>
  
  <p>Does anyone know where, or how, in the 'slick.js' code, the width of a  carousel slide is calculated, <strong>when 'variableWidth' is set to false?</strong></p>
  
  <p>Thanks.</p>
