title: In Vue.js, how to set a piece of data to always equal the containing element's height?
body: <p>I'm trying to bind a piece of data to always equal the containing element's height. The height changes due to other user interactions (i.e. window resize). </p>
  
  <p>Within a computed property, when I try to access the <code>this.$el</code> field, the element hasn't been properly set up yet.</p>
  
  <p>So I'm wondering if there's any way to gracefully set a piece of data to always equals a dom element's height.</p>
