title: Why use long decimal point values in CSS percentage widths?
body: <p>I've noticed in my own work that 3 fluid columns fill out their parent element much better when their widths are set to 33.333% as opposed to just 33%. I've also noticed when researching various CSS frameworks (i.e. bootstrap.css) that they have 14 decimal places specified on their column widths! That seems like it would be either excessive or clever... but I don't know which.</p>
  
  <p>So what is the value/benefit of having so many decimal places? From what I have gathered, there is an open debate on whether you should avoid decimal places or take advantage of them and I want to know if this should be of interest to me or to just not worry about it.</p>
