title: Input a double range of values with start and end values
body: <p>I have to select some values in a range, with a start and an end value, like in this image example :
  <img src="https://i.stack.imgur.com/ZSZej.png" alt="enter image description here"></p>
  
  <p>I search with <code>&lt;input type="range"&gt;</code> HTML element, but it can't have two selectors.</p>
  
  <p>I can use <strong>JavaScript</strong> (even a library if a natural way doesn't exist) or <strong>PHP</strong>, and of course <strong>HTML</strong> and <strong>CSS</strong>. I didn't find anything like that, so you are my last hope.</p>
  
  <p>Do you know something ?</p>
  
  <p>P.S.: I know I could use two basics inputs, but it is a client wish to have a graphical unique input like that.</p>
