title: Can I change the media query using javascript / jQuery?
body: <p>I have a style.css with a media query. In my javascript-file, I have a value for the desired mobile-width stored in a variable.</p>
  
  <p>By changing the variable, I want to change the value of the media query automatically. Is it somehow possible to alter the contents of the .css-file with javascript like I can change the DOM? 
  Adding a HTML <code>&lt;style&gt;</code>-element to the DOM using javascript is not my desired solution, because I want to keep all css in the .css-file</p>
