Center content in post without text-align: center

Hi! As the title says, i would like to center conten in a single post. I can use text-align: center; and it works fine, except that the text are not justified, so looking for an alternative. Here is an example of content i would like to center: https://www.harbourmagazine.se/2013/02/07/hm-x-brick-lane-bikes/

Any ideas?
