<h1>Animation of flex</h1>
<p>Gradually change the flex property of the BLUE div element from 1 to 3, and back:<p>
<div id="main">
  <div style="background-color:coral;">RED</div>
  <div style="background-color:lightblue;" id="myBlueDiv">BLUE</div>  
  <div style="background-color:lightgreen;">GREEN</div>
</div>
<p><b>Note:</b> Internet Explorer 10 supports an alternate, the -ms-flex property. IE11 and newer versions fully support the flex property (do not need the -ms- prefix).</p>
