WP Google Map Fullwidth

Hey guys!

I have the issue that my map seems to be fullwidth on a smaller browser window, but as soon as I open up the window it stops scaling and is left aligned, leaving an ugly white space on the right. Any ideas? I tried already with custom code:

#map .container {
width: 100%;
padding: 0;
margin: 0;
}
#top #main #map.avia-section .template-page {
padding: 0;
}

thanks in advance!
