Center Team Members if one 2 are displayed

Hello Guys

I wonder whether you could help me out with an issue i encounter on one of my hosted websites https://www.p-p-g.ch
I use the [Himalayas] page template and its widget to display the team members. However, if i choose to display only 2 (instead of the standard 3) team members, the members are not aligned in the center. I would like to center-align the 2 team members to make the page look more professional.

Could you please help me? How can i center-align the 2 Team Members on my page: https://www.p-p-g.ch/ (direkt link: https://www.p-p-g.ch/#team ) ? Is there a CSS-Code i might be able to use?

Thank you very much for your help!!
Looking forward to your answers.

Best regards
