Hi,
I would like the image to fit in the amended size as it seems to have cropped.
I used object fit but it still doesn’t look right, I need the images to look like the attached photo.
Also how do I apply the background colours appropriately? Do I need to create seperate div boxes for each different colour?

we need a bit more code then that 
anyway if u want to make ure project like the site bellow follow these links about positioning your images
https://www.w3schools.com/css/css_positioning.asp
https://www.w3schools.com/csS/css_align.asp
as for the background collor u can just make a body-background element in css and then use the bellow guide for the colors

the picture you seemed to post looks like it is just using the images into the boxes not the colors again can’t tell you much without the code
