Can anyone help me figure out how to fix the weird spacing on the right side of this three-column layout? I can’t figure out why there is more spacing on the right side of the main image than the far left image. It may be the left image that is off.
You missed sharing your read-only link. What I can guess is, you have an external or internal margin on whether the center or right children element.
I would suggest to get rid of those, set the main div/container to: Flex horizontal, Stretch, Space between, and add a gap that would work as the main spacer.
The issue with the uneven spacing between your elements is because the images are not taking the full width of their parent container, leaving empty space. To fix this, set the width of the images to 100%.
