title: Get the height of a Component in React
body: <p>I have 4 columns, none of whose height is fixed, and I need to find the height of these columns so that the height of the largest column can be set to the other three. How can I do this with React and not using the 'minHeight' css?</p>
  
  <p>I am a newbie in React and the closest question I found here was <a href="https://stackoverflow.com/questions/31661790/reactjs-get-rendered-component-height">ReactJS get rendered component height</a>.</p>
  
  <p>Also I found <a href="http://facebook.github.io/react/docs/top-level-api.html#reactdom.finddomnode" rel="nofollow noreferrer">this</a> link which says that this could be done by getting the DOMNode and using the Refs, but I'm with no success.</p>
