Web Forms/Control Structures

I need help with Lab Assignment 2 and also with alignments when navigating from page to page when it comes to the footer, header, and navigation links on the left side of page when clicking between the different links. I thought I was doing it right but I was told I can fix the alignments of it in the CSS file but not sure how I am able to do it. It looks good on my end but if you use different computers with different screen sizes the alignments ends up being off. It is not supposed to shift when navigating from page to page. I sent you an attachment of the instructions and the grade sheet of how it is being graded. Also, I am sending a doc of what was done with the last Assignment 1 that has the headers, footer, and navigations to help with the alignments. The CSS file though can’t be the same for this one it has to be new.
