  <p>What do I need? First I have a problem with margin, negative margin.
  I need the to item be full width 33.3%</p>
  <p>To solve the negative margins.</p>
  <p>I want each item to be exactly 33.3% and to be full length. It's 32% for me at the moment, and if I set it to 33.3%, it's a shortcut to a new line.</p>
