title: HTML5 input type range from positive to negative
body: <p>Is there any way to allow a positive minimum and a negative maximum? I am trying to create the slider in log space (10^8-10-13) and want to show the exponent on the slider. </p>
  
  <pre><code>&lt;input  type="range" min="8" max='-13' value="1" step="-1" id="myRange" &gt;
  </code></pre>
  
  <p>This currently reverts to the default <code>max=100</code> value.</p>
  
  <p>Or perhaps can I reverse the slider in some way? Any help would be much appreciated. </p>
  
  <p>EDIT: Please remember I want the scale to be DECREASING from 8 to -13 (log space 10^8-10^-13).</p>
  
  <p>EDIT: In IDL xr=[8,-13] (or R xlim=c(8,-13)). Note that the minimum value is a positive and the max is a negative number, and you can step between the two accordingly. I am asking for help with a workaround to create the same behaviour with the input type range.</p>
