In my attempts on understanding grids, I’ve failed to fully comprehend how to fit a larger image to the predetermined size of the grid, which would reduce size of the image. My image enlarges the grid Box1 instead and, by default box2,3,4, and 5 are pushed further out. Which can be seen when zoomed out. I've been lurking for 2 days now on similar project like mine and used their solutions, however, does not seem to stick to mine A couple of solutions I’ve read:
Edited, for grammar.
Variable image height in Nested Grid UWP Resize image in grid to fit div to smaller size Controlling the size of an image within a CSS Grid layout Control size of images in nested grid layouts containing the image inside a css grid

The problem is that the img is an actual element taking up space.
This snippet removes that div and img and instead puts the image as a background with size cover. This ensures that box1 remains the size given by the grid settings.

To avoid the image to resize the grid (or overflow it) you can set its size to 0 and min-size to 100%
example
img {
height:0;
width:0;
min-height:100%;
min-width:100%;
object-fit:cover
}
