title: Can we provide fxLayoutGap value in varibale?
body: <p>I need to provide fxLayoutGap value in variable instead of directly number. Below code for your reference:</p>
  
  <p>ex: fivepix = '5px';</p>
  
  <p><code>&lt;div fxLayoutGap="5px"&gt;&lt;/div&gt;</code></p>
  
  <p><code>&lt;div fxLayoutGap="fivepix"&gt;&lt;/div&gt;</code></p>
  
  <p>Like above can we declare it?</p>
