Trouble displaying the theme correcly on mobile

Hi there!

I am using the Clarina theme because it really looks good. Everything works as described (I also changed the bug that failed to display the “Team” section.

On desktop it looks really well, but on mobile there seems to be an issue. First discovered on mobile, the page width seems to be twice the width of the actual content.

Also on desktop, (Chrome) when selecting “inspect element” the menu on the right appears. When this happens, somehow the width of the content seems to be half the page width. When using full screen on browser however, it works fine.

I have been struggling for hours now in the CSS but somehow I can’t figure out what is going on. Does anyone know what is going on and how to fix this?

You help is greatly, GREATLY appreciated since I am getting desperate.

Thanks!
