Something I'm doing wrong with the docking position. When I position the container by the side of an image, they align perfectly in their positions but when I published the container goes up some pixels more than the image position. I've tried many positions in the docking point square but no success. Does anybody can help me and tell me what I'm doing wrong? I want to justify the three containers.
This is the result. When I published it.

This is in the canvas

Thanks in advance for your help.
Hi @edquijano,
By looking at your screenshots, it appears that the image is docked to the bottom whereas the containers are docked to the top. So remove 'Dock to bottom' from the image if it is docked to the bottom and dock it to the top instead.
