Como você pode ver na imagem, tenho o botão de zoom in zoom out no canto inferior esquerdo da tela. Quero fazê-lo subir um pouco ou talvez adicionar um novo css para ele, para que seja mais fácil de usar. Alguém pode me ajudar com isso, como mudar este?

Obrigado e cumprimentos

Adicionado o seguinte script para

$(window).bind( 'orientationchange', function(e){
    var ori = window.orientation ;
        w = (ori==90 || ori==-90) ? screen.height : screen.width;
        h = (ori==90 || ori==-90) ? screen.width : screen.height;
         $('#map-canvas').width(w);
         $('#map-canvas').height($(window).height()- $('#head1').height());


    });

resulta em
