I know this is an incredibly silly question, but here it goes:
I want the header, top-left navigation links, as well as the left edge of text/image posts in my Tumblr blog to start off at the same exact position as the header logo and images in my Cargo website's main page. That is, start off from the left at the same time. This means that the Tumblr posts should become wider while keeping their right edge, margins, etc. in the same exact position. How do I go about doing that? Any help is appreciated.
