Adobe Portfolio- adds padding to images side by side

Needing some advice- in Adobe Portfolio, I am looking for the pages to display at the same 90% width but when I add images side by side the folio site adds its own padding which makes them display wider (as seen in the image below). It's fine on mobile device but not on web, I have tried inserting them as photo grids but then on mobile the images arn't as big as I would like them.

Any help would be appreciated! Thanks
