One-page theme, adding new section

Hi, I am learning grav and am using one-page theme . I want to make a new section for example a section (or a page) called my-team which has the basic layout of my team section in a modular page with all the images, sliders, etc.
I tried copying and team.html.twig from other skeletons but it just doesn’t align itself properly in the one-page theme and makes the content looks weird and scattered.

for simplification i have added a link of my team section(the core-team part) that i wish to put on my site.
