title: Is there any way to define absolute position of a widget in ipywidgets?
body: <p>I would like to define some widgets at absolute position within a layout in ipywidgets. The Box layout in ipywidgets allows me to add children but only in a sequential way. For example, I want to put button 2 at lower right corner of button 1, but the following codes only place button 2 after button 1.</p>
  <pre><code>import ipywidgets as widgets
  box = widgets.Box(layout=widgets.Layout(width='400px', height='200px'))
  button1 = widgets.Button(layout=widgets.Layout(top='30px', left='20px', width='100px', height='30px'), description=&quot;Button1&quot;)
  button2 = widgets.Button(layout=widgets.Layout(top='60px', left='120px', width='100px', height='30px'), description=&quot;Button2&quot;)
  box.children += (button1, button2)
  box
  </code></pre>
  <p>I tried the following command but fail to make the widget use the absolute position.</p>
  <pre><code>button2 = widgets.Button(layout=widgets.Layout(position=&quot;absolute&quot;, top='60px', left='120px', width='100px', height='30px'), description=&quot;Button2&quot;)
  </code></pre>
  <pre><code>button2.style.position = &quot;absolute&quot;
  </code></pre>
  <p>Is there any way to put widgets at absolute position?</p>
