Styling related posts

He there,

Im trying to center the ‘featured image’ in my related posts on a blog page. Is there anyone who can help me with the right css code?

I just can’t find the right code to change :(.

Example, here you see that the logo is on the left side and on the top. I want to center this one.

Thanks in advance!
