How to left-align text but keep blog post centred on the blog overview page

I'd like to keep the posts and titles centre-aligned on the blog overview page, but have the text left-aligned so it's easier to read.

Please see my site here: https://www.saraharnoldhall.com/blogging

You'll see I have many blog posts when you scroll down.

Would love some help, please!

Hey! 

hopefully someone can help with this, i was just looking at the site on mobile it looks awesome! 🙂 really great design! 

with regards to the posts on mobile and from a graphic designer/typography perspective i think the posts would look great if the title and the text are left aligned.  personally i think that flows and helps legibility - Of course its design so it’s all subjective. its just a thought whilst viewing on mobile 

i know im not answering the question exactly, but i wanted to mention just as an alternative option. hope that’s ok 😊

Thank you so much that worked!!!
