CSS

Hi team, would you be kind to help me out with some CSS for my GeoDirectory on my site?
1. On the main directory page, the map doesn’t extend all the way to the edges of the site as it usually does. The map shows within a container, how do I make it go all the way to the
sides?
2. Can the search bar be made to be in the centre, perhaps with the button color as in

This is on Directory Starter theme which looks proper.
2. Can I put a CSS to remove to header text and subheader text to not appear as it’s not neccessary and just takes up space.
3. The place page is on the left side of the page with the sidebar kinda in the middle, leaving a lot of empty space on the right. Can I centralize the whole thing, as in

This one uses you Directory Starter theme which looks very nice, but I need to use the GD with my LMS Press theme.
4. I’d like to make the background light grey for the places page.
5. You’ll see the ‘My Dashboard’ text is a bit chopped off on the top. (image attached)

I tried GD a separate wordpress in my subdomain (directory.pastrybake.com) and ran it on Directory Starter theme and GD looks good that way. But I need to customize the design to look nice on my LMS Press theme. I appreciate your help.
