   }
   pre:nth-of-type(1) {
      overflow: hidden;
   }
   pre:nth-of-type(1)::before {

<body>
<pre> 
Some say the world will end in fire,
Some say in ice.
From what I've tasted of desire
I hold with those who favour fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
