section text and image / image and text

Hi,
For a new project, i'd like to do something like that https://www.thalesgroup.com/fr/career/nos-metiers
Behind the header, the "section" are made with text and an image, the section behing image and text without any margin. I'd like to create the same structure but i don't know if "section" is the good way (with lightweight grid columns).
Do you have any suggestions ?
Thanks
