You could always try giving each line that you want justified a class such as
, then do a middle and bottom class and adjust the letter spacing and the word spacing until it looks how you want. Here’s a very simple example http://codepen.io/anon/full/fnCkL. Hope this kind of helps.
Without playing around with letter spacing etc … And just focusing on 1 line of text. Is there a method which will ‘span/stretch/justify’ a headline to a specific width. So I want 1 headline to span 620px for instance?
