Page Margins Full Width

Hi my site is and I am trying to make the pages be full width left to right on all pages. So maybe reduce the margins. Example, on the home page, I need the logo to be all the way in the left corner and not have that additional margin space next to it. Same with the menu items on this page to be all the way to the right with no margin space next to it, same with the content on all pages and footer. Also, need the images on Gallery page to cover the whole page left to right. Currently, there is margin space to the left and right of the image rows. Any solution for this?

Please close, I have another post open with the same question.
