Responsiveness of my site in map

hi guys
I’ve made a site
when I resize the screen all the elemnts become smaller due to resposive design of it … except the google map!
is there any way to resize the maps when resizing the screen or not???!!!
you can see my site in here to check it

your map its already responsive.

I think what you want its something like this to make the place center on the map even if you resize the page.
