Content shown in Desktop view, not visible on tablet or mobile views

OK thank you so much for communicating… client wanted a large picture on homepage as a banner only… other pages have lots of info so I am hoping to scroll down to trigger different sections on the page??? 1/3 only showing … I would like to remove the blank spaces between content but only want one section to show at a time…

whole site is to be Responsive … needing tablet and ph views as well… noticed almost all content is not showing up in other breakpoint views…

Do I have to start with a smaller PICTURE on home page and remove strange margins and paddings so mobile devices auto show up or can we make this work where I am at…?

Not sure what to call the sections / containers etc divs to make the Aboutus page perform the way I wish … any and all ideas are welcomed… with videos and documentation…

I getting behind on this project… bruceo
