I'have https://icj.mx/ website, if I use a sigle picture like in an image addon like this https://icj.mx/Uno.png when I try to see in a celullar the image is very small and I cant read the text, One solution is divide this image in two parts, the left one is an image and the right part is a text addon with a image background in a 6+6 section. But this is the result https://icj.mx/dos.png

How can I eliminate the blank space between two addons. If I use a backgrownd color or image in sections the image hace a margin in color arroundit and I do not want it.

Regards
