By default, the One Tap prompt is displayed in the top-right corner of desktop
web browser windows. When FedCM is used, browser fully controls the
prompt location. Hence, custom layouts are not supported.
Otherwise, display One Tap inside a container element to change prompt position.
To do so, specify the DOM ID of the container element in the
data-prompt_parent_id attribute.
The following code example reuses the g_id_onload element as the container
element and displays the One Tap prompt in the specified position:
