Single/Double side environment with different backgrounds.(help needed)

Single/Double side environment with different backgrounds.(help needed)

I'm having troubles aligning some of the elements.
I would like to have Check Box and Cross Box to be same size and align so that they look nicer then what i got so far.
Also it would be great if they can change in size with respect to environment with (some ratio 60% of text or so)
[Optional] have background so that it would be easer to reed.(did not look at this one yet working on aligning check boxes )
Thank you for your help in advance!
