title: How to increase slider length in ipywidgets
body: <p>Suppose, I have the following code:</p>
  <pre><code>from ipywidgets import interact, interactive
  import ipywidgets as widgets
  
  def f(x):
      return x
  interact(f, x=(0,10,1));
  </code></pre>
  <p>The resulting interactive slider is nice but pretty small in terms of horizontal length. When the range of x is large, such as 0 - 1000, it becomes exceedingly difficult taking small steps using that slider. How can I increase the length of the slider?</p>
