Hide shadow on infowindow in Google Map API V3

Question

I want to hide the shadow on infowindow in Google Map API V3. I try to access the Floatshadow pane but I don't know how to do it.

Answer 1

<style type="text/css">
img[src*="iws3.png"] {
    display: none;
}
</style>

Answer 2

Try something like the InfoBubble library. It's not possible to do this within the API itself.

edit: As of v3.11, info windows don't have shadows by default.
