I hav been following the instructions on this WPMUDEV

Hi, I hav been following the instructions on this WPMUDEV tutorial:
https://premium.wpmudev.org/blog/how-to-create-a-custom-buddypress-members-directory/

But the end result is in the screenshot I have provided. My membe's pictures are left sided and so are the "title"
How can I make my member pictures and their titles be "centered" rather than left sided?
