CSS fix for text overflowing black border

The hits/models.py file was generating a <div> nested in another
<div>, where the width of both <div>'s was set to 100%:

  <div style=" width:100%; border:2px solid black; margin-top:10px">
    <div style="width:100%; margin:10px">

With the 10px margin, text in the inner <div> was overflowing the
boundaries of the outer <div>.  Removing the second "width: 100%"
fixes the overflow issue.
