css selector for .x-map marker image

[macs]

i would like to use a css animated user location marker. What would be the css selector for that? I another non sencha app of mine I just used the selector below which works fine.

#map_canvas div.gmnoprint[title="I might be here"] {

#mymap_canvas div.gmnoprint[title="i am here"]:not([title]) {
}

i tried the following without success

.x-map  div.gmnoprint[title="i am here"]:not([title]) {
}

how would i select the marker in sencha touch?

[macs]

i got it/ it was not a sencha problem/ i had to set the optimized property of the marker to false
