Align title centered in template in stead of left.

Hi!
I am working on a wordpress site with the theme https://themeforest.net/item/lobo-portfolio-for-freelancers-agencies/full_screen_preview/7762848. On a desktop and on the tablet the title (on the big photo) is aligned on the left side of the page. On a phone, this title is centered. I want to have the title centered everywhere. What text do I need to change from ‘left’ to ‘center’ in the css?
Thanks!
