title: gap between two 50% width divs
body: <p>I have a container <code>&lt;div&gt;</code> with a width of 181px.</p>
  
  <p>I have two child <code>&lt;div&gt;</code> elements in my container div each with a width of 50%.</p>
  
  <p>My problem is that each of my child <code>&lt;div&gt;</code> elements has a width of only 90px, resulting in a 1px gap between the two.</p>
  
  <p>Any suggestions for removing the gap?</p>
