Room Homepage && Ecom site

I had a bit of trouble setting up the grid for the home page so the buttons for the carousel don't line up correctly they constantly move out of place, I'm still fairly new to css GRID and flex box so any suggestions on how to fix this would be great also if you have any ideas of things I can add to the ecom site ( the rest of the sites display is set for mobile as I'm still planing the tablet and desktop views ) it would be greatly appreciated!
