title: Is there any reason why the pseudoelements ::after and ::before don't work in Foundation?
body: <p>I'm using Foundation 6 for Sites to create a responsive site. 
  I failed to use pseudoelements ::after and ::before (I didn't forget about the content property).
  My browser code inspector shows no pseudoelements and they are not implemented on the page.</p>
  
  <p>Any ideas why it has happened and how to deal with it?
  May it be a trouble with sass?</p>
