title: Split html between two divs?
body: <p>I have two divs. Both are 400 px height. User enters text in WYSIWYG editor. 
  I need to split this HTML text in a way that div #1 is filled first and when it's full (no more text will fit) I need to start appending to another div.</p>
  
  <p>It it was plain text I would split it on newlines and then line by line I would copy to <code>div #1</code> and, when it's full, to <code>#div 2</code>.
  But since it's HTML I don't know how to split it.</p>
  
  <p>I cannot use CSS columns because I need different styles for each column.</p>
