Mapbox Block position Absolute vs Relative

Site URL: https://www.ese-llc.com/harwichma

I have added the code for a mapbox map in my site.  https://www.ese-llc.com/harwichma
Position: relative results in the map on the site.  It works, the click is in the right spot but there is a gap between the ads and the map.
Position: absolute results in the map being tight to the ads (which is what I want) but the click is offset by what would appear to be the gap difference.  Somewhat annoying to click a parcel and get something to the north.
Any thoughts?

I figured it out.  I stuck with relative and changed the margin-top to -175px.
