      <p>Update 2016 - This has been fixed - YAY! :)</p>   
<p>UPDATE 2015-11-25 -- It looks like a fix for this is in the pipeline: <a href="">Chromium issue details</a>. Yay!</p>      
			<p>Try resizing this page, the border between two colours should be smooth in most browsers with the dotted line and colour interface matching up. In Chrome the position of the colour change is incorrect and jumps around</p>
      <p>According to <a href="">this bug</a> it is due to Chrome splitting the gradient into 256 sections, and so getting rounding down errors.</p>
      <p>Discovered via <a href="">this Stack Overflow question</a></p>
      <p>Update: Chrome 43 the jumping has been reduced ... but compare this page in Chrome and IE / Firefox to see the difference in rendering.</p>
