Help me with code, please!

Hi. I understand that the page constructors can be heavy and slow down the load of the pages and that is why you do not recommend them. But many of us do not have a great command of HTML or CSS and in that case, how do you suggest that we solve problems such as eliminating the space that I show in the link, so that the photo is stuck right at the edge of the bottom column? Could you give me some solution through code? Or failing which plugin do you recommend to be the lightest to avoid these problems?
